Methods We conducted a multicentre hospital study. A development cohort consisting of patients from three hospitals was used to identify the predictors of osteoporotic fracture through univariate and multivariable logistic regression analyses and to construct a nomogram. The C-statistic, calibration plot, and decision curve analysis were calculated to evaluate discrimination, calibration, and clinical usefulness of the nomogram, respectively. The nomogram was further validated in the validation cohort (1 hospital) and internally validated by bootstrap. Results A total of 27,658 patients were enrolled from January 2018 to December 2022. Osteoporotic fracture was confirmed in 15,324 (71.2%) of 21,525 and 4,030 (65.7%) of 6,133 in development and validation cohorts respectively. Gender, increased age, urbanization, osteoporosis, hypoproteinemia, Parkinson’s disease, hypertension, heart failure, and chronic kidney disease were independent risk factors for osteoporotic fracture. The C-statistic was 0.82 (95% CI , 0.81–0.82) based on the development cohort. Similar C-statistic values were achieved during internal (0.82 [95% CI , 0.81–0.82]) and external validation (0.71 [95% CI , 0.70–0.73]). Calibration plots were well fitted and DCA curves indicated that the clinical validity of the model was best when the threshold probability was 0.4–1.0. Conclusion The nomogram established in this study could better predict the risk of osteoporotic fracture. After considering and discussing the prediction with patients, physicians can establish a rational therapeutic plan.

With the increase in the mean life expectancy and aging, the incidence of OP and related fragility fractures continue to increase, which has become another cause of inestimable harm to the health of the elderly after chronic diseases, such as hypertension and diabetes [ 2 ] . A previous study reported that approximately 158 million people aged > 50 years were at high risk of OF in 2010 worldwide and this number will double by 2040 [ 3 ] . The latest epidemiological survey in China showed that the prevalence rate of OP in people aged > 65 years is as high as 32%, including 10.7% in males and 51.6% in females [ 4 ] . The prevalence of vertebral fractures in men aged > 40 years was 10.5%, similar to that in women [ 5 ] . Within 1 year, 39% of patients with hip fractures have moderate disabilities, 26% of women and 13% of men will refracture, and the mortality of both men and women has more than tripled [ 6 – 7 ] . Despite the high incidence of OF, the diagnosis and treatment of pre-fracture osteoporosis are significantly inadequate, with only 1.4% of women and 0.3% of men osteoporosis patients receiving anti-osteoporotic treatment to prevent fragility fractures [ 5 ] . In addition, the use of direct medical resources during fractures and indirect cost consumption will have a significant socioeconomic burden. In Europe, osteoporosis and its 4.3 million fragility fractures cost the healthcare system more than 56 billion euros a year [ 8 ] . The high morbidity, mortality, disability, and economic burden of OF emphasize the necessity of early identification of patients and continuous management; therefore, its prevention and treatment have become a research topic for many scholars. Although an increasing number of risk factors have been documented, these studies only explored the individual effect of these factors and ignored the interaction impact of various factors on disease progression, with limited accuracy. In addition, the prediction of fracture risk mostly depends on imaging parameters such as bone mineral density. However, it is particularly difficult to obtain image information in rural and township areas where medical conditions are insufficient and prevention concepts are lacking, and evaluation tools without imaging are needed to detect high-risk groups of early fracture. Clinical prediction model is a mathematical model established for estimating the probability of occurrence of a disease based on a variety of risk factors, which can accurately assess the risk according to individual characteristics. Therefore, this study retrospectively collected the demographic characteristics and comorbidities data of patients, developed and validated a nomogram for predicting the risk of OF, which can be used to screen high-risk groups to provide a reference for clinical diagnosis, treatment, and disease prevention. Participants and methods Study design and population This retrospective, multicenter observational study was conducted in 4 hospitals (Hebei Medical University Third Hospital, North China Medical Xingtai General Hospital, the Second Hospital of Tangshan and Jingxing County Hospital). This retrospective study conforms to the principles of the Declaration of Helsinki. Every human participant provide their consent. The study design was approved by the Ethics Committee of the Third Hospital of Hebei Medical University (Approval Number: K2020-022-1). Clinical trial number: not applicable. Patients from Hebei Medical University Third Hospital from January 2020 to December 2022 were enrolled, and the remaining hospitals from January 2018 to December 2020 were enrolled. We enrolled patients with fractures aged ≥ 65 years according to the following inclusion and exclusion criteria. Inclusion criteria: (1) age of ≥ 65 years, (2) diagnosis of fracture. Exclusion criteria: (1) multiple fractures, (2) open fractures, (3) pathological fractures caused by tumors, (4) old or secondary fractures, and (5) missing complete medical records and imaging data. The enrolled cases were divided into a modeling cohort and a validation cohort. The modeling cohort was composed of three hospitals (Hebei Medical University Third Hospital, the Second Hospital of Tangshan, Jingxing County Hospital), and the validation cohort was composed of one hospital (North China Medical Xingtai General Hospital) for external validation (Fig. 1 ). Data collection and study outcomes By consulting medical records and telephone follow-ups, we collected the following research contents: (1) demographic characteristics, including gender, age, ethnic origin, occupation, urbanization; (2) characteristics of injury, including fracture history, cause and location of injury; and (3) comorbidities, including OP, rheumatoid arthritis, diabetes, vitamin D deficiency, hypoproteinemia, Parkinson’s disease, epilepsy, hypertension, heart failure, coronary atherosclerotic heart disease, thyroid or parathyroid disease, asthma, chronic obstructive pulmonary disease (COPD), and chronic kidney disease. The patients were divided into three groups: 65–74, 75–84 and ≥ 85years. The outcome was OF, defined as hip, distal radius, proximal humerus, or vertebral fracture caused by low-energy injury in people aged 65 and older [ 9 ] . Low-energy injury was defined as injury caused by similar behaviors, such as falls from standing height or low altitude (< 1 m) and falls on a bicycle. Thus, patients were divided into the OF and non-OF group. Statistical analysis Descriptive statistics were reported as frequencies and proportions, cause the collected factors were all categorical variable. Differences between proportions were assessed using the χ 2 test or Fisher exact probability test. The baseline characteristics of the development and validation cohorts were compared. In the development cohort, univariable logistic analysis was used to identify the relevant variables associated with OF. Variables showing P < 0.1 were entered into multivariable logistic regression model, and forward stepwise selection was performed. Nomogram were derived from the multivariable model to predict the individual risk of OF. The C-statistic and receiver operating curve (ROC) were calculated to assess the ability of the nomogram to distinguish patients who are prone to OF. The C-statistic was compared with that of each independently associated variable in the development cohort. Calibration plots were created to analyze the agreement between the nomogram predictions and actual observations. Decision curve analysis (DCA) was performed to evaluate the clinical usefulness of the nomogram by quantifying net income under different OF occurrence threshold probabilities. Bootstrap resampled 1000 times were done to calculate the C-statistic as internal validation. To assess external validity, the model was applied to an independent external dataset from 1 hospital. C-statistic, calibration plot and DCA were calculated. All statistical analyses were performed using R4.1.0 (R Foundation for Statistical Computing, Austria). All P values were two-sided, and less than 0.05 was considered statistically significant. Results Characteristics of fracture cases A total of 27,658 patients were eligible for inclusion and exclusion in this study: 21,525 were assigned to the development cohort including 15,324 (71.2%) patients were confirmed with OF, and 6,133 patients to the validation cohort including 4,030 (65.7%) were confirmed with OF. The mean ± SD age was74.3 ± 7.7 years old and there were 9,939 (35.9%) males and 17,719 (64.1%) females with a male-to-female ratio of 1:1.8. As shown in Fig. 2 , With the increase OF age, the proportion of OF increased continuously, and the proportion of females was always higher than that of males, increasing from 40.8–66.2%, and that of males increased from 15.7–29.3%. The baseline characteristics of development and validation cohorts were shown in Table 1 . Table 1 Demographic and clinical characteristics of development cohort and validation cohort.

Based on the final multivariable model, a nomogram was generated by the “Plot” function of R (Fig. 3 ). In practical application, the risk of OF can be determined based on the relevant variables of the individual, for example, a 76-year-old female living in a rural area, without any illness. If we got the score on the nomogram according to the value of each factor, the risk of OF in this female was 0.91.

In the development cohort, the nomogram for predicting OF had a C-statistic of 0.82 (95% CI , 0.81–0.82), which was significantly higher than the C-statistic obtained for each variable in the model (Fig. 4 A) (Table 3 ). The C-statistic remained stable in the internal (0.82 [95% CI , 0.81–0.82)) and external (0.71 [95% CI , 0.70–0.73]) validations, which indicated that the model had a good to distinguish OF patients from non-OF patients (Fig. 4 B). We will use 0.912 as the cut-off point of the model for risk classification. When the probability of an individual developing osteoporotic fracture (OF) predicted by the model is greater than or equal to 0.912, the individual will be classified as being at high risk; when the predicted probability is less than 0.912, the individual will be classified as being at low risk. At this cut-off point, the sensitivity of the model is 0.784, which means that the model can correctly identify 78.4% of individuals who actually have osteoporotic fractures; the specificity is 0.577, that is, the model can correctly identify 57.7% of individuals who actually do not have osteoporotic fractures. The model has certain discriminative performance. In the calibration plots of development and validation cohorts, the apparent line and correction line coincided with the ideal line, indicating that the predicted risk of the nomogram was consistent with the actual risk of OF. The U statistic is used to test the goodness of fit of the calibration. With a P-value of 1.000, it indicates that the model performs well in terms of calibration, and the predicted probability is quite consistent with the actual occurrence probability, which enhances the reliability of the model (Fig. 5 ). According to the DCA, when the threshold probability was in the range of 0.4-1.0, the net benefit of the model was higher than that of the entire treated population and the entire untreated population, which means that the model has the best predictive effect(Fig. 6 ). Table 3 C-statistics for the nomogram and model variables in the development cohort C-statistic(95% CI ) P Nomogram 0.817(0.811 to 0.822) - Gender 0.631(0.624 to 0.638) < 0.001 Age(years) 0.710(0.705 to 0.716) < 0.001 Urbanization 0.527(0.520 to 0.535) < 0.001 OP 0.597(0.593 to 0.600) < 0.001 Parkinson’s disease 0.505(0.504 to 0.506) < 0.001 Hypoproteinemia 0.534(0.530 to 0.538) < 0.001 Hypertension 0.558(0.551 to 0.565) < 0.001 Heart failure 0.503(0.502 to 0.504) < 0.001 Chronic kidney disease 0.513(0.511 to 0.515) < 0.001 Discussion In this study, we developed and validated a nomogram to predict OF. The nomogram, based on female, increased age, urbanization, OP, hypoproteinemia, Parkinson’s disease, hypertension, heart failure, and chronic kidney disease, had a discriminatory ability (C-statistic) of 0.82 (95% CI , 0.81–0.82) in predicting OF. It also exhibited stable performance in internal and external validations, and the accuracy of the prediction was confirmed by the calibration plots. Bone mineral density is often an indispensable variable in fracture risk prediction models, and it contributes significantly to the accuracy and stability of prediction results. However, in practical application, due to the lack medical conditions and prevention concepts in rural and township areas, the universal acquisition of bone mineral density parameters is hindered, and it is slightly difficult to apply such tools. The use of other easily accessible factors for risk prediction is a potential strategy to expand the detection population and increase the availability of tools. The prediction model based on demographic characteristics and combined diseases is simpler and easier to operate in practice. Gender and age are recognized as risk factors for OF. Previous studies have shown that the risk of OF in women is 12.33 times higher than that in men (aged > 50 years) [ 10 ] , which is consistent with our findings. Rapid depletion of postmenopausal estrogen is the main reason for the decrease in bone mass in elderly women. Estrogen is a recognized bone-protective hormone that plays a key role in regulating the bone microenvironment, targeting osteoblasts, osteoclasts, and cytokines that regulate bone mass. Although the risk of initial fracture is higher in women than in men, the risk of refracture may be higher in men than in women [ 11 ] . Overall, the risk of fracture significantly increased with age in both men and women, and the risk of OF in people aged ≥ 75 years was two to five times higher than that in people aged < 75 years. The increase in age is accompanied by a decline in physical function and hormone levels and is prone to not only fractures but also complications during treatment, increasing the complexity and risk of treatment. Further studies found that there are different trends in the prevalence of OF between men and women, and the prevalence of postmenopausal fractures in women increases exponentially, whereas the occurrence of this phenomenon in men is delayed for 10 years [ 12 ] , which may be due to the slow decline in sex hormones in men and the rapid decline in women [ 13 ] . The present study shows that living in rural areas can reduce the risk of OF, which is consistent with the findings of Brennan et al. [ 14 ] . The mortality rate after fracture is the same as this phenomenon [ 15 ] . In general, residents in rural areas engage in more physical activity, and an active lifestyle can increase muscle strength and postural stability in the face of accidents. At the same time, the open-air working environment increased the level of serum vitamin D with an increase in sunshine, and serum vitamin D is the key factor affecting BMD. Moreover, urban residents have a higher level of comorbidities [ 16 ] . Concomitant diseases lead to more fragile bones or bodies, increase the possibility of falls, and increase the probability of fractures. Comorbidities have an important effect on bone quality. In our study, OP was an independent risk factor for OF. The predictive accuracy of OP alone was represented by a C-statistic of 0.60 in the development cohort, showing that OP itself had moderate discriminative power. Hypertension is a common chronic disease in the elderly, with a prevalence rate of 44.7% in people aged 60–69 years and 70.4% in those aged > 70 years [ 17 ] . Increased urinary calcium excretion in patients with hypertension reduces the amount of calcium in the process of bone remodeling, and long-term calcium homeostasis injury reduces BMD [ 18 ] . In addition to the effects of the disease itself, the use of antihypertensive drugs can also damage bones [ 19 ] . In agreement with previous research, Parkinson’s disease associated with falls was also included because previous studies suggested that falls is a risk factor for fracture [ 20 – 21 ] . Hypoproteinemia was a risk factor for OF in our study; however, the mechanism between changes in serum protein homeostasis and OF is not fully understood [ 22 – 27 ] . Our results are consistent with previous findings, that heart failure is associated with an approximately 30% increase in major OF that is independent of traditional risk factors [ 28 ] . Chronic kidney disease affects bone health because of its effect on mineral metabolism in, resulting in an increased risk of fractures. Hip fracture risk may be as much as four-fold higher in the worst affected [ 29 ] . A history of fracture is significantly associated with an increased risk of impending fracture [ 30 – 31 ] . After immobilization in bed, patients with fracture quickly develop bone loss and aggravate osteoporosis, thus increasing the risk of fracture, forming a vicious circle, and having an impact by worsening their general health status. This finding is inconsistent with our multiple factors analysis results. This may be related to the inclusion of the population. This study is located in a provincial capital city, where the economy is more developed. Compared with the areas where the economic level lags behind, the patients included differed in nutrition level, medical conditions, and health attention. This may have affected the previous fracture level, thus affecting the results of this study. Previous studies have shown that the vertebral body is the most common site of osteoporotic fractures, which is slightly different from the current study. In our study, approximately four of five patients had hip fractures (79.9%) and vertebral compression fractures (9.0%), and the rest of the proximal humerus and distal radius were 6.0% and 5.2%, respectively. The geographical environment, socioeconomic level, and lifestyle may be part of the reason for this phenomenon. For individuals at risk of osteoporotic fractures, anti - osteoporosis medications should be actively prescribed. Meanwhile, nutritional supplementation should be enhanced. They should increase protein intake and ensure sufficient calcium and vitamin D intake. For patients with Parkinson's disease, hypertension, heart failure, and chronic kidney disease, strict compliance with medical advice is required to control the progression of underlying diseases. In terms of lifestyle, patients are encouraged to engage in appropriate weight - bearing exercises and muscle - strengthening training to improve body balance and reduce the risk of falls and subsequent fractures caused by physical function problems. Regarding the living environment of patients, potential fall - causing obstacles such as ground debris and loose carpets should be removed. When necessary, appropriate assistive devices should be provided according to the specific physical conditions of patients to prevent falls. In addition, clinical symptoms of patients, such as low back pain and height loss, should be closely and regularly evaluated. These comprehensive measures can reduce the risk of osteoporotic fractures in high - risk patients and improve their quality of life. Compared with the previously published nomogram [ 32 – 33 ] , this model used a much larger development cohort and completed the external validation, and had good accuracy and stability in model evaluation. However, our study has several limitations. First, information bias was inevitable in this retrospective study. Second, although the population of four hospitals was included to establish and validate the model, these hospitals were all limited to Hebei Province. If we want to obtain a universally applicable model, we need the participation of a larger range of people. Conclusions In conclusion, our nomogram is simple to use and able to identify patients with a high probability of OF. After considering and discussing the prediction with patients, physicians can establish a rational therapeutic plan and these patients might benefit from early triage and more intensive monitoring.

In addition, the prediction of fracture risk mostly depends on imaging parameters such as bone mineral density. However, it is particularly difficult to obtain image information in rural and township areas where medical conditions are insufficient and prevention concepts are lacking, and evaluation tools without imaging are needed to detect high-risk groups of early fracture.

Based on the final multivariable model, a nomogram was generated by the \u0026ldquo;Plot\u0026rdquo; function of R (Fig.\u0026nbsp;\u003cspan refid=\"Fig3\" class=\"InternalRef\"\u003e3\u003c/span\u003e). In practical application, the risk of OF can be determined based on the relevant variables of the individual, for example, a 76-year-old female living in a rural area, without any illness. If we got the score on the nomogram according to the value of each factor, the risk of OF in this female was 0.91.\u003c/p\u003e\u003cp\u003e\u003cdiv class=\"gridtable\"\u003e\u003ctable

of the model\u003c/b\u003e\u003c/p\u003e\u003cp\u003eWe assessed the discrimination of the final model using C-statistics. In the development cohort, the nomogram for predicting OF had a C-statistic of 0.82 (95%\u003cem\u003eCI\u003c/em\u003e, 0.81\u0026ndash;0.82), which was significantly higher than the C-statistic obtained for each variable in the model (Fig.\u0026nbsp;\u003cspan refid=\"Fig4\" class=\"InternalRef\"\u003e4\u003c/span\u003eA) (Table\u0026nbsp;\u003cspan refid=\"Tab3\" class=\"InternalRef\"\u003e3\u003c/span\u003e). The C-statistic remained stable in the internal (0.82 [95%\u003cem\u003eCI\u003c/em\u003e, 0.81\u0026ndash;0.82)) and external (0.71 [95%\u003cem\u003eCI\u003c/em\u003e, 0.70\u0026ndash;0.73]) validations, which indicated that the model had a good to distinguish OF patients from non-OF patients (Fig.\u0026nbsp;\u003cspan refid=\"Fig4\" class=\"InternalRef\"\u003e4\u003c/span\u003eB). We will use 0.912 as the cut-off point of the model for risk classification. When the probability of an individual developing osteoporotic fracture (OF) predicted by the model is greater than or equal to 0.912, the individual will be classified as being at high risk; when the predicted probability is less than 0.912, the individual will be classified as being at low risk. At this cut-off point, the sensitivity of the model is 0.784, which means that the model can correctly identify 78.4% of individuals who actually have osteoporotic fractures; the specificity is 0.577, that is, the model can correctly identify 57.7% of individuals who actually do not have osteoporotic fractures. The model has certain discriminative performance. In the calibration plots of development and validation cohorts, the apparent line and correction line coincided with the ideal line, indicating that the predicted risk of the nomogram was consistent with the actual risk of OF. The U statistic is used to test the goodness of fit of the calibration. With a P-value of 1.000, it indicates that the model performs well in terms of calibration, and the predicted probability is quite consistent with the actual occurrence probability, which enhances the reliability of the model (Fig.\u0026nbsp;\u003cspan refid=\"Fig5\" class=\"InternalRef\"\u003e5\u003c/span\u003e). According to the DCA, when the threshold probability was in the range of 0.4-1.0, the net benefit of the model was higher than that of the entire treated population and the entire untreated population, which means that the model has the best predictive effect(Fig.\u0026nbsp;\u003cspan refid=\"Fig6\" class=\"InternalRef\"\u003e6\u003c/span\u003e).\u003c/p\u003e\u003cp\u003e\u003cdiv

this study, we developed and validated a nomogram to predict OF. The nomogram, based on female, increased age, urbanization, OP, hypoproteinemia, Parkinson\u0026rsquo;s disease, hypertension, heart failure, and chronic kidney disease, had a discriminatory ability (C-statistic) of 0.82 (95%\u003cem\u003eCI\u003c/em\u003e, 0.81\u0026ndash;0.82) in predicting OF. It also exhibited stable performance in internal and external validations, and the accuracy of the prediction was confirmed by the calibration plots.\u003c/p\u003e\u003cp\u003eBone mineral density is often an indispensable variable in fracture risk prediction models, and it contributes significantly to the accuracy and stability of prediction results. However, in practical application, due to the lack medical conditions and prevention concepts in rural and township areas, the universal acquisition of bone mineral density parameters is hindered, and it is slightly difficult to apply such tools. The use of other easily accessible factors for risk prediction is a potential strategy to expand the detection population and increase the availability of tools. The prediction model based on demographic characteristics and combined diseases is simpler and easier to operate in practice.\u003c/p\u003e\u003cp\u003eGender and age are recognized as risk factors for OF. Previous studies have shown that the risk of OF in women is 12.33 times higher than that in men (aged\u0026thinsp;\u0026gt;\u0026thinsp;50 years) \u003csup\u003e[\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e]\u003c/sup\u003e, which is consistent with our findings. Rapid depletion of postmenopausal estrogen is the main reason for the decrease in bone mass in elderly women. Estrogen is a recognized bone-protective hormone that plays a key role in regulating the bone microenvironment, targeting osteoblasts, osteoclasts, and cytokines that regulate bone mass. Although the risk of initial fracture is higher in women than in men, the risk of refracture may be higher in men than in women \u003csup\u003e[\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]\u003c/sup\u003e. Overall, the risk of fracture significantly increased with age in both men and women, and the risk of OF in people aged\u0026thinsp;\u0026ge;\u0026thinsp;75 years was two to five times higher than that in people aged\u0026thinsp;\u0026lt;\u0026thinsp;75 years. The increase in age is accompanied by a decline in physical function and hormone levels and is prone to not only fractures but also complications during treatment, increasing the complexity and risk of treatment. Further studies found that there are different trends in the prevalence of OF between men and women, and the prevalence of postmenopausal fractures in women increases exponentially, whereas the occurrence of this phenomenon in men is delayed for 10 years \u003csup\u003e[\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]\u003c/sup\u003e, which may be due to the slow decline in sex hormones in men and the rapid decline in women \u003csup\u003e[\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]\u003c/sup\u003e.\u003c/p\u003e\u003cp\u003eThe present study shows that living in rural areas can reduce the risk of OF, which is consistent with the findings of Brennan et al. \u003csup\u003e[\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e]\u003c/sup\u003e.

In general, residents in rural areas engage in more physical activity, and an active lifestyle can increase muscle strength and postural stability in the face of accidents. At the same time, the open-air working environment increased the level of serum vitamin D with an increase in sunshine, and serum vitamin D is the key factor affecting BMD. Moreover, urban residents have a higher level of comorbidities \u003csup\u003e[\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e]\u003c/sup\u003e. Concomitant diseases lead to more fragile bones or bodies, increase the possibility of falls, and increase the probability of fractures.\u003c/p\u003e\u003cp\u003eComorbidities have an important effect on bone quality. In our study, OP was an independent risk factor for OF. The predictive accuracy of OP alone was represented by a C-statistic of 0.60 in the development cohort, showing that OP itself had moderate discriminative power. Hypertension is a common chronic disease in the elderly, with a prevalence rate of 44.7% in people aged 60\u0026ndash;69 years and 70.4% in those aged\u0026thinsp;\u0026gt;\u0026thinsp;70 years \u003csup\u003e[\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]\u003c/sup\u003e.

After immobilization in bed, patients with fracture quickly develop bone loss and aggravate osteoporosis, thus increasing the risk of fracture, forming a vicious circle, and having an impact by worsening their general health status. This finding is inconsistent with our multiple factors analysis results. This may be related to the inclusion of the population. This study is located in a provincial capital city, where the economy is more developed. Compared with the areas where the economic level lags behind, the patients included differed in nutrition level, medical conditions, and health attention. This may have affected the previous fracture level, thus affecting the results of this study. Previous studies have shown that the vertebral body is the most common site of osteoporotic fractures, which is slightly different from the current study. In our study, approximately four of five patients had hip fractures (79.9%) and vertebral compression fractures (9.0%), and the rest of the proximal humerus and distal radius were 6.0% and 5.2%, respectively. The geographical environment, socioeconomic level, and lifestyle may be part of the reason for this phenomenon.\u003c/p\u003e\u003cp\u003eFor individuals at risk of osteoporotic fractures, anti - osteoporosis medications should be actively prescribed. Meanwhile, nutritional supplementation should be enhanced. They should increase protein intake and ensure sufficient calcium and vitamin D intake. For patients with Parkinson's disease, hypertension, heart failure, and chronic kidney disease, strict compliance with medical advice is required to control the progression of underlying diseases. In terms of lifestyle, patients are encouraged to engage in appropriate weight - bearing exercises and muscle - strengthening training to improve body balance and reduce the risk of falls and subsequent fractures caused by physical function problems. Regarding the living environment of patients, potential fall - causing obstacles such as ground debris and loose carpets should be removed. When necessary, appropriate assistive devices should be provided according to the specific physical conditions of patients to prevent falls. In addition, clinical symptoms of patients, such as low back pain and height loss, should be closely and regularly evaluated. These comprehensive measures can reduce the risk of osteoporotic fractures in high - risk patients and improve their quality of life.\u003c/p\u003e\u003cp\u003eCompared with the previously published nomogram \u003csup\u003e[\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e]\u003c/sup\u003e, this model used a much larger development cohort and completed the external validation, and had good accuracy and stability in model evaluation.

A development cohort consisting of patients from three hospitals was used to identify the predictors of osteoporotic fracture through univariate and multivariable logistic regression analyses and to construct a nomogram. The C-statistic, calibration plot, and decision curve analysis were calculated to evaluate discrimination, calibration, and clinical usefulness of the nomogram, respectively. The nomogram was further validated in the validation cohort (1 hospital) and internally validated by bootstrap.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e\u003cp\u003eA total of 27,658 patients were enrolled from January 2018 to December 2022. Osteoporotic fracture was confirmed in 15,324 (71.2%) of 21,525 and 4,030 (65.7%) of 6,133 in development and validation cohorts respectively. Gender, increased age, urbanization, osteoporosis, hypoproteinemia, Parkinson\u0026rsquo;s disease, hypertension, heart failure, and chronic kidney disease were independent risk factors for osteoporotic fracture. The C-statistic was 0.82 (95%\u003cem\u003eCI\u003c/em\u003e, 0.81\u0026ndash;0.82) based on the development cohort. Similar C-statistic values were achieved during internal (0.82 [95%\u003cem\u003eCI\u003c/em\u003e, 0.81\u0026ndash;0.82]) and external validation (0.71 [95%\u003cem\u003eCI\u003c/em\u003e, 0.70\u0026ndash;0.73]). Calibration plots were well fitted and DCA curves indicated that the clinical validity of the model was best when the threshold probability was 0.4\u0026ndash;1.0.\u003c/p\u003e\u003ch2\u003eConclusion\u003c/h2\u003e\u003cp\u003eThe nomogram established in this study could better predict the risk of osteoporotic fracture.
