However, there are no effective clinical diagnostic indicators for PEBV-IM. The study aimed to construct a clinical model for effective prediction of PEBV-IM and to identify relevant key feature variables, thereby providing a favorable clinical decision-making tool for PEBV-IM. Methods Data were obtained from the clinical diagnosis of PEBV-IM patients, and the feature variables were acquired by least absolute shrinkage and selection operator (LASSO) regression analysis. Subsequently, optimal clinical prediction models and key feature variables for PEBV-IM were acquired using 6 machine learning (ML) algorithms. Finally, to further investigate the relationship between optimal clinical prediction models and key feature variables, the SHapley Additive exPlanations (SHAP) model interpretation was proceeded. Results A total of 60 PEBV-IM samples and 41 variables were included in the analyses, and 12 characteristic feature variables were identified by LASSO. Subsequently, founded on the feature variables, the clinical prediction model was constructed using the plsRglm algorithm, which achieved the highest accuracy in both the training set (area under the curve (AUC) = 0.939) and the validation set (AUC = 0.850). Thus, this model was identified as the optimal clinical prediction model, while key feature variables platelet count and gamma-glutamyl transferase (GGT) were acquired. Notably, the GGT had the significant effect on the output of the clinical prediction model, with low GGT having a positive effect on the output, while low feature values of platelet count had a negative effect on the model output. Conclusion Obtaining a highly accurate clinical prediction model for PEBV-IM and 2 key feature variables (platelet count and GGT), which, in combination with SHAP model interpretation, provided a clear understanding and a novel tool for early diagnosis and clinical decision-making in PEBV-IM.

Introduction Epstein-Barr virus (EBV), also known as human herpesvirus 4(HHV-4), is a member of the gamma herpesvirus family that infects over 95% of the world's population 1 . EBV was first identified in Burkitt lymphoma (BL) in 1964 and was later found to be associated with other types of lymphoma, including Hodgkin lymphoma (HL), non-HL, T cell lymphoma, and natural killer (NK)/T cell lymphoma in posttransplant patients and HIV infected individuals. EBV is also linked to epithelial cancers, such as nasopharyngeal carcinoma (NPC) and gastric cancers. Additionally, EBV is associated with nonmalignant diseases, including infectious mononucleosis (IM), oral hairy leukoplakia, systemic lupus erythematosus (SLE), and multiple sclerosis (MS) 2 . Although several preventive or therapeutic vaccine strategies for EBV have been evaluated in clinical and preclinical trials, no licensed vaccines or therapeutic interventions for EBV-associated diseases 3–5 . Primary EBV infection is often asymptomatic, but when the immune response is strong, the resulting disease state is called IM. Patients with symptomatic IM typically experience the classic triad of fever, lymphadenopathy, and pharyngitis 6,7 , along with other symptoms such as transient hepatitis, splenomegaly, malaise, nausea, and palatal petechiae, depending on the host's response to the invading virus 8 . Painless bilateral swelling of the upper eyelids 9,10 and thrombocytopenia 11–13 may also occur. Although IM is a self-limiting disease and symptoms usually resolve within weeks, fatigue may persist for months. Early, accurate laboratory results are essential for the correct diagnosis of IM, allowing for timely intervention and avoiding unnecessary treatments, such as antibiotics for pharyngitis symptoms or expensive exploratory tests for cases with splenomegaly or suspicious hematological disease 14 . Therefore, reliable diagnostic metrics and clinical predictive models are crucial for effective decision-making in PEBV-IM. Machine Learning (ML) enables computer systems to learn from data, improve performance, and make predictions or decisions by identifying patterns and building mathematical models. Common methods used in clinical prediction models include linear regression, logistic regression, support vector machines, decision trees, random forests, neural networks. These methods can process large-scale and complex data, improve prediction accuracy, personalize treatment, and provide real-time decision-making tools for PEBV-IM. Based on clinical and pathological data collected from PEBV-IM patients, this study constructs a clinical predictive model for PEBV-IM using bioinformatics analysis and multiple ML algorithms, identifying key variables related to PEBV-IM. This model provides a valuable decision-making tool for PEBV-IM, enabling early intervention and personalized treatment. 2. Materials and methods 2.1 Data collection and processing Data on clinical characteristics of pediatric Epstein-Barr virus (EBV) infectious mononucleosis (PEBV-IM) patients were collected from Xi'an Children's Hospital, and informed consent was obtained from the patient’s guardian for the used of the data. Firstly, the PEBV-IM dataset contained information on totally 99 cases with the disease, subsequently, variables with null data (days to EBV diagnosis, cluster of differentiation 25 (CD25), natural killer (NK) cell activity), variables with only one status (lymph node enlargement, history of immunosuppression or not), and variables with too large a disparity in sample size (sore throat / pharyngeal isthmus (yes: 97, no: 2), presence of haemophilia on bone puncture (not investigated: 95, yes: 2, no : 2)) were excluded. Finally, the 39 samples in which EBV load were not checked were excluded, a sum of 60 samples and 41 variables included in the analysis ( Supplementary Table 1 ). 2.2 Baseline characteristics analysis The PEBV-IM dataset was first split into training and validation sets in a 7: 3 ratio by random splitting. Subsequently, so as to assess whether there were marked differences in the clinical feature variables between the training and validation sets. Subsequently, the quartile method 15 was adopted to split continuous variables into categorical variables (Q1-Q4), and the Mann-Whitney U test was applied to compare differences in clinical characteristics. Then, the chi-square test was applied to compare the differences in clinical characteristics of categorical variables, excluding variables with marked in the both dataset (p < 0.05). 2.3 Construction of clinical prediction models To identify feature variables for predicting PEBV-IM, founded on training set, the aspartate aminotransferase (AST) / alanine aminotransferase (ALT) was designated as the dependent variable (to be 0 for less than the median and 1 for greater than the median). Then, the glmnet package (v 4.1-8) 16 was adopted to proceed 10-fold cross-validation least absolute shrinkage and selection operator (LASSO) regression analysis. The variables with the smallest model error and the regression coefficient not penalized to 0 were selected as the feature variables. Moreover, founded on the feature variables, the NaiveBayes, RF, SVM, Ridge, plsRglm and LDA algorithms from e1071 package (v 1.7–14), 17 randomForestSRC package (v 3.3.0) 18 , e1071 package (v 1.7–14), glmnet package (v 4.1-8), plsRglm package (v 1.5.1) 19 , and MASS package (v 7.3–60.0.1 https://cran.r-project.org/web/packages/MASS/index.html ) were applied to construct the clinical predictive models, respectively. Subsequently, in the training and validation sets, the pROC package (v 1.18.0) 20 was applied to evaluate the accuracy of predictive models by plotting receiver operating characteristic (ROC) curves, and the optimal clinical predictive model of PEBV-IM with the highest the area under curve (AUC) values in both datasets was selected. Further, founded on the optimal clinical prediction model, the key feature variables were acquired. 2.4 SHapley Additive exPlanations (SHAP) model interpretation So as to better understand the relationship between the key feature variables and the clinical prediction model, the shapviz package (v 0.9.5) 21 was applied to compute the mean |SHAP| values of the key feature variables and to acquire distribution of feature importance. Subsequently, the key feature variables were ranked in descending order of importance founded on the mean |SHAP| values of the key feature variables, the ggplot2 package (v 3.4.2) 22 was applied to visualize the results. Moreover, the impact of single key feature variables on the optimal clinical prediction model results was observed. 2.5 Statistical analysis All statistical analyses were conducted using R software (v 4.3.1). The Mann-Whitney U test and chi-square test were utilized to evaluate paired sample comparisons, with statistical significance defined as p < 0.05. 3. Results 3.1 The 39 variables were applied in subsequent analyses A sum of 60 PEBV-IM samples and 41 variables were included in the study, with the training set and validation set containing 47 and 13 PEBV-IM samples, respectively. Then, the results of the baseline characteristics analysis displayed that the T cells and Ts cells count were markedly different in the training and validation sets (p 0.05) and could be applied for subsequent analyses (Table 1 ). 3.2 The optimal clinical predictive models and key characteristic variables were obtained In the training set, founded on the 39 variables, 12 feature variables were acquired by LASSO regression analysis (log(lambda.min) = -2.9235 (Fig. 1 A, B), namely age, gender, degree of splenomegaly, percentage of lymphocytes, red blood cells count, hemoglobin, platelet count, GGT, helper T (Th) cells count, B cells count, interleukin (IL)-1 beta (IL-1β) and IL-10 (Table 2 ). Subsequently, 6 clinical prediction models were acquired founded on the construction of 12 feature variables (Table 3 ), and it could be observed that the clinical prediction model constructed by plsRglm had the highest AUC values in the training (AUC = 0.939) and validation sets (AUC = 0.850) (Fig. 2 A-C), which was the optimal clinical predictive model for PEBV-IM. Furthermore, platelet count and GGT were identified as key feature variables.

platelet count affected model output The SHAP values could determine the difference between the predicted values for all combinations, by calculating the mean |SHAP| values, it could be observed that the GGT had the greatest effect on the clinical prediction model output (Fig. 3 A). In addition, the effect of features on the model output was explored, the results displayed that samples with high GGT feature values had a negative effect on the prediction, and samples with low GGT feature values had a positive effect on the prediction. On the feature values of platelet count, a low feature values had a negative effect on the model output and conversely a positive effect (Fig. 3 B). Finally, by focusing on the dependence between platelet count and GGT, it was found that both had a linear relationship with the model’s predictions. This indicated that the predictions were not only affected by the level of each key feature variable but also by the individual differences between them (Fig. 3 C). Overall, the interpretability and transparency of the clinical prediction model was improved by SHAP interpretation, which enabled used to better understand the predictive results of the model for PEBV-IM risk prediction. 4. Discussion EBV infection is a widespread condition that affects nearly all tissues and organs in the body 23 , 24 , with systemic effects on the liver, blood and immune system in EBV-associated diseases 25 – 27 . Despite its prevalence, there is a critical lack of reliable predictive models for early identification and intervention in IM, particularly in pediatric populations. The present study addresses this gap by constructing a clinical predictive model using 6 ML algorithms, providing a powerful tool for early diagnosis and intervention in PEBV-IM. Most primary EBV infections manifest as IM in the pediatric population, and in a few cases, they progress to more severe conditions like EBV-associated hemophagocytic lymphohistiocytosis (HLH) 28 . Huang R et al. 29 used LASSO regression and logistic regression analysis to identify risk factors and independent predictors for EBV, while also constructing nomograms to assist in early detection. In addition, a small minority of individuals may develop chronically active Epstein-Barr virus (CAEBV) infection, after EBV infection, leading to a disease prone to relapse and associated with severe and potentially fatal comorbidities such as malignant lymphoma, HLH, multiple organ failure, and disseminated intravascular coagulation (DIC) 30 , 31 . Yuan JH et al. 32 enhanced their results by applying LASSO Logistic regression to identify key peripheral blood biomarkers that distinguish IM from CAEBV, thus offering valuable guidance for clinical work. Both studies highlight the reliability of LASSO as a high-dimensional predictor regression method 33 . Similarly, in this study, 39 clinical variables were initially analyzed, with 12 characteristic variables identified through LASSO regression analysis. This led to the construction of 6 clinical predictive models, ultimately identifying GGT and platelet count as key characteristic variables for predicting PEBV-IM. GGT is a glycosylated protein located on the outer plasma membrane, a microsomal enzyme involved in the homeostasis of glutathione and cysteine 34 . GGT plays a crucial role in transferring glutamyl from gamma-glutamate to other peptides, and although its activity in the kidney is ten times higher than in the liver, serum GGT is typically used as a liver test 35 . Studies have shown that about 85% of EBV-infected patients experience varying degrees of liver impairment, with some cases leading to hepatitis, which increases transaminase levels and impairs liver function 36 . HeHC et al. 37 observed consistently elevated GGT levels in EBV-infected gastric cancer patients, while ZhangL 38 found GGT to be significantly higher in IM patients than in healthy controls, demonstrating its diagnostic and predictive value. These findings are consistent with our results, where high GGT characteristics were negatively associated with the prediction of IM, indicating that patients with higher GGT levels are more likely to be diagnosed with IM and experience longer hospital stays. Monitoring GGT can thus help help identify patients at greater risk and allow for early intervention. Platelet are essential for coagulation and the repair of vascular endothelial cells, with significant decreases in platelet count leading to spontaneous bleeding, which can be life-threatening in some severe cases 39 . Previous studies have suggested that IM can cause thrombocytopenia in children 40 . A recent study reported by Zhang et al described a 14-year-old girl who developed severe thrombocytopenia (with a platelet count down to 5×10 9 /L), leading to spontaneous bleeding and periorbital edema, a rare symptom of IM 41 . Yan et al. reported EBV-DNA positivity in blood lymphocytes of patients with chronic immune thrombocytopenia (detected by quantitative reverse transcription PCR) higher than controls 42 . LiY et al. 43 found in a study that EBV-DNA copy number in plasma can be used as an important indicator to assess the duration of fever and clinical outcomes in children. These researches showed that platelet counts correlate with EBV-DNA copy number in plasma, suggesting that this indicator can be used to assess the duration of fever and clinical outcomes in children. HanX et al. 44 used regression analysis to analyze the predictive value of platelet four indicators in IM patients, and established three regression models for regression analysis, showing that PLT is a significant predictor of IM. LinJ et al. 45 proposed in their study that L and platelet count < 50 × 10 12 /L are independent risk factors for mortality in CAEBV patients. PrtorićL et al. 46 reported in a recent article that each unit decrease in platelet count increases hospital stay by 0.12 days, so platelet count is a predictor of hospital stay. Our study supports these findings, with low platelet eigenvalues negatively impacting the model output, and vice versa. That is, the lower the platelet number, the more severe the child's condition and the longer the hospital stay. Therefore, platelet count can be used to clinically assess the severity of IM in children, helping clinicians identify those at risk and intervene early. In this study, we developed the best clinical predictive model for PEBV-IM through 6 ML methods, particularly the plsRglm model. However, a major challenge in the medical application of ML models is the lack of interpretability 47 . To address this, we introduced SHAP values, which were proposed by Lundberg et al. 48 for accurately calculating the contribution and impact (positive or negative) of each feature on the final prediction. SHAP can perform both local and global interpretability and has a solid theoretical foundation compared to other methods 49 . In this study, SHAP values allowed us to better understand the impact of key characteristic variables (GGT and platelet count) on the model output. Interestingly, the relationship between GGT and platelet count was linear, with higher GGT characteristic value and lower platelet characteristic value being associated with more severe IM. This further emphasizes that predictions were influenced not only by the level of each key characteristic variable but also by their individual differences between them. ML, especially in healthcare, holds great promise in handling large, complex datasets to improve predictions. Greener JG 50 highlighted the importance of matching predictive models to data and automating analysis to build repeatable and time-saving pipelines. ML algorithms are particularly useful when dealing with vast amounts of clinical data, as demonstrated by their widespread application in discovering diagnostic markers and predicting disease outcomes 51 . Our study highlights the potential of ML in clinical settings, particularly for identifying key biomarkers and predicting disease progression in IM patients. This could ultimately lead to more personalized and effective treatments. Despite the promising results, there are several limitations in this study that warrant consideration. First, the sample size is relatively small, which may limit the generalizability and robustness of the model. Larger and multi-center studies are needed to validate the findings and enhance the model's applicability across diverse clinical settings. Second, some variables were missing in the dataset, which could introduce bias into the analysis. Lastly, while ML models are powerful tools, their complexity and the difficulty in interpreting results may hinder their repeatability and widespread use in clinical practice. Future research should focus on improving the model’s interpretability, expanding the clinical data set, and conducting clinical trials to verify its real-world applicability. In conclusion, our study demonstrates the potential of ML in creating an effective predictive model for PEBV-IM. The identification of key characteristic variables (GGT and platelet count) provides valuable insights for early diagnosis and intervention. By integrating these predictive tools into clinical practice, we can improve patient outcomes through more personalized and timely interventions. Future studies should aim to refine and validate these models for broader clinical use.

Introduction","content":"\u003cp\u003eEpstein-Barr virus (EBV), also known as human herpesvirus 4(HHV-4), is a member of the gamma herpesvirus family that infects over 95% of the world's population\u003csup\u003e1\u003c/sup\u003e. EBV was first identified in Burkitt lymphoma (BL) in 1964 and was later found to be associated with other types of lymphoma, including Hodgkin lymphoma (HL), non-HL, T cell lymphoma, and natural killer (NK)/T cell lymphoma in posttransplant patients and HIV infected individuals. EBV is also linked to epithelial cancers, such as nasopharyngeal carcinoma (NPC) and gastric cancers.\u003c/p\u003e\n\u003cp\u003eAdditionally, EBV is associated with nonmalignant diseases, including infectious mononucleosis (IM), oral hairy leukoplakia, systemic lupus erythematosus (SLE), and multiple sclerosis (MS)\u003csup\u003e2\u003c/sup\u003e. Although several preventive or therapeutic vaccine strategies for EBV have been evaluated in clinical and preclinical trials, no licensed vaccines or therapeutic interventions for EBV-associated diseases\u003csup\u003e3\u0026ndash;5\u003c/sup\u003e.\u003c/p\u003e\n\u003cp\u003ePrimary EBV infection is often asymptomatic, but when the immune response is strong, the resulting disease state is called IM. Patients with symptomatic IM typically experience the classic triad of fever, lymphadenopathy, and pharyngitis\u003csup\u003e6,7\u003c/sup\u003e, along with other symptoms such as transient hepatitis, splenomegaly, malaise, nausea, and palatal petechiae, depending on the host's response to the invading virus\u003csup\u003e8\u003c/sup\u003e.

that the GGT had the greatest effect on the clinical prediction model output (Fig.\u0026nbsp;\u003cspan class=\"InternalRef\"\u003e3\u003c/span\u003eA). In addition, the effect of features on the model output was explored, the results displayed that samples with high GGT feature values had a negative effect on the prediction, and samples with low GGT feature values had a positive effect on the prediction. On the feature values of platelet count, a low feature values had a negative effect on the model output and conversely a positive effect (Fig.\u0026nbsp;\u003cspan class=\"InternalRef\"\u003e3\u003c/span\u003eB). Finally, by focusing on the dependence between platelet count and GGT, it was found that both had a linear relationship with the model\u0026rsquo;s predictions. This indicated that the predictions were not only affected by the level of each key feature variable but also by the individual differences between them (Fig.\u0026nbsp;\u003cspan class=\"InternalRef\"\u003e3\u003c/span\u003eC).

Studies have shown that about 85% of EBV-infected patients experience varying degrees of liver impairment, with some cases leading to hepatitis, which increases transaminase levels and impairs liver function\u003csup\u003e\u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e\u003c/sup\u003e. HeHC et al.\u003csup\u003e37\u003c/sup\u003e observed consistently elevated GGT levels in EBV-infected gastric cancer patients, while ZhangL\u003csup\u003e\u003cspan citationid=\"CR38\" class=\"CitationRef\"\u003e38\u003c/span\u003e\u003c/sup\u003e found GGT to be significantly higher in IM patients than in healthy controls, demonstrating its diagnostic and predictive value. These findings are consistent with our results, where high GGT characteristics were negatively associated with the prediction of IM, indicating that patients with higher GGT levels are more likely to be diagnosed with IM and experience longer hospital stays. Monitoring GGT can thus help help identify patients at greater risk and allow for early intervention.\u003c/p\u003e \u003cp\u003ePlatelet are essential for coagulation and the repair of vascular endothelial cells, with significant decreases in platelet count leading to spontaneous bleeding, which can be life-threatening in some severe cases\u003csup\u003e\u003cspan citationid=\"CR39\" class=\"CitationRef\"\u003e39\u003c/span\u003e\u003c/sup\u003e. Previous studies have suggested that IM can cause thrombocytopenia in children\u003csup\u003e\u003cspan citationid=\"CR40\" class=\"CitationRef\"\u003e40\u003c/span\u003e\u003c/sup\u003e. A recent study reported by Zhang et al described a 14-year-old girl who developed severe thrombocytopenia (with a platelet count down to 5\u0026times;10\u003csup\u003e9\u003c/sup\u003e/L), leading to spontaneous bleeding and periorbital edema, a rare symptom of IM\u003csup\u003e41\u003c/sup\u003e. Yan et al. reported EBV-DNA positivity in blood lymphocytes of patients with chronic immune thrombocytopenia (detected by quantitative reverse transcription PCR) higher than controls\u003csup\u003e\u003cspan citationid=\"CR42\" class=\"CitationRef\"\u003e42\u003c/span\u003e\u003c/sup\u003e. LiY et al.\u003csup\u003e43\u003c/sup\u003e found in a study that EBV-DNA copy number in plasma can be used as an important indicator to assess the duration of fever and clinical outcomes in children. These researches showed that platelet counts correlate with EBV-DNA copy number in plasma, suggesting that this indicator can be used to assess the duration of fever and clinical outcomes in children. HanX et al.\u003csup\u003e44\u003c/sup\u003e used regression analysis to analyze the predictive value of platelet four indicators in IM patients, and established three regression models for regression analysis, showing that PLT is a significant predictor of IM. LinJ et al.\u003csup\u003e45\u003c/sup\u003e proposed in their study that L and platelet count\u0026thinsp;\u0026lt;\u0026thinsp;50 \u0026times; 10\u003csup\u003e12\u003c/sup\u003e/L are independent risk factors for mortality in CAEBV patients. PrtorićL et al.\u003csup\u003e46\u003c/sup\u003e reported in a recent article that each unit decrease in platelet count increases hospital stay by 0.12 days, so platelet count is a predictor of hospital stay. Our study supports these findings, with low platelet eigenvalues negatively impacting the model output, and vice versa. That is, the lower the platelet number, the more severe the child's condition and the longer the hospital stay. Therefore, platelet count can be used to clinically assess the severity of IM in children, helping clinicians identify those at risk and intervene early.\u003c/p\u003e \u003cp\u003eIn this study, we developed the best clinical predictive model for PEBV-IM through 6 ML methods, particularly the plsRglm model. However, a major challenge in the medical application of ML models is the lack of interpretability\u003csup\u003e\u003cspan citationid=\"CR47\" class=\"CitationRef\"\u003e47\u003c/span\u003e\u003c/sup\u003e. To address this, we introduced SHAP values, which were proposed by Lundberg et al.\u003csup\u003e48\u003c/sup\u003e for accurately calculating the contribution and impact (positive or negative) of each feature on the final prediction. SHAP can perform both local and global interpretability and has a solid theoretical foundation compared to other methods\u003csup\u003e\u003cspan citationid=\"CR49\" class=\"CitationRef\"\u003e49\u003c/span\u003e\u003c/sup\u003e. In this study, SHAP values allowed us to better understand the impact of key characteristic variables (GGT and platelet count) on the model output. Interestingly, the relationship between GGT and platelet count was linear, with higher GGT characteristic value and lower platelet characteristic value being associated with more severe IM. This further emphasizes that predictions were influenced not only by the level of each key characteristic variable but also by their individual differences between them.\u003c/p\u003e \u003cp\u003eML, especially in healthcare, holds great promise in handling large, complex datasets to improve predictions. Greener JG\u003csup\u003e50\u003c/sup\u003e highlighted the importance of matching predictive models to data and automating analysis to build repeatable and time-saving pipelines. ML algorithms are particularly useful when dealing with vast amounts of clinical data, as demonstrated by their widespread application in discovering diagnostic markers and predicting disease outcomes\u003csup\u003e\u003cspan citationid=\"CR51\" class=\"CitationRef\"\u003e51\u003c/span\u003e\u003c/sup\u003e. Our study highlights the potential of ML in clinical settings, particularly for identifying key biomarkers and predicting disease progression in IM patients. This could ultimately lead to more personalized and effective treatments.\u003c/p\u003e \u003cp\u003eDespite the promising results, there are several limitations in this study that warrant consideration. First, the sample size is relatively small, which may limit the generalizability and robustness of the model. Larger and multi-center studies are needed to validate the findings and enhance the model's applicability across diverse clinical settings. Second, some variables were missing in the dataset, which could introduce bias into the analysis. Lastly, while ML models are powerful tools, their complexity and the difficulty in interpreting results may hinder their repeatability and widespread use in clinical practice. Future research should focus on improving the model\u0026rsquo;s interpretability, expanding the clinical data set, and conducting clinical trials to verify its real-world applicability.\u003c/p\u003e \u003cp\u003eIn conclusion, our study demonstrates the potential of ML in creating an effective predictive model for PEBV-IM. The identification of key characteristic variables (GGT and platelet count) provides valuable insights for early diagnosis and intervention. By integrating these predictive tools into clinical practice, we can improve patient outcomes through more personalized and timely interventions. Future studies should aim to refine and validate these models for broader clinical use.\u003c/p\u003e"},{"header":"Abbreviations","content":"\u003ctable border=\"0\" cellspacing=\"0\"

However, there are no effective clinical diagnostic indicators for PEBV-IM. The study aimed to construct a clinical model for effective prediction of PEBV-IM and to identify relevant key feature variables, thereby providing a favorable clinical decision-making tool for PEBV-IM.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eData were obtained from the clinical diagnosis of PEBV-IM patients, and the feature variables were acquired by least absolute shrinkage and selection operator (LASSO) regression analysis. Subsequently, optimal clinical prediction models and key feature variables for PEBV-IM were acquired using 6 machine learning (ML) algorithms. Finally, to further investigate the relationship between optimal clinical prediction models and key feature variables, the SHapley Additive exPlanations (SHAP) model interpretation was proceeded.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eA total of 60 PEBV-IM samples and 41 variables were included in the analyses, and 12 characteristic feature variables were identified by LASSO. Subsequently, founded on the feature variables, the clinical prediction model was constructed using the plsRglm algorithm, which achieved the highest accuracy in both the training set (area under the curve (AUC)\u0026thinsp;=\u0026thinsp;0.939) and the validation set (AUC\u0026thinsp;=\u0026thinsp;0.850). Thus, this model was identified as the optimal clinical prediction model, while key feature variables platelet count and gamma-glutamyl transferase (GGT) were acquired. Notably, the GGT had the significant effect on the output of the clinical prediction model, with low GGT having a positive effect on the output, while low feature values of platelet count had a negative effect on the model output.\u003c/p\u003e\u003ch2\u003eConclusion\u003c/h2\u003e \u003cp\u003eObtaining a highly accurate clinical prediction model for PEBV-IM and 2 key feature variables (platelet count and GGT), which, in combination with SHAP model interpretation, provided a clear understanding and a novel tool for early diagnosis and clinical decision-making in PEBV-IM.\u003c/p\u003e","manuscriptTitle":"Clinical prediction models for pediatric Epstein-Barr virus infectious mononucleosis: from 6 machine learning algorithms Running Title: Machine learning Models for Pediatric EBV Infectious Mononucleosis","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-02-11 05:25:36","doi":"10.21203/rs.3.rs-8437947/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"editorInvitedReview","content":"","date":"2026-02-16T02:13:55+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"230630741464645983441209498889362369550","date":"2026-02-05T23:28:07+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2026-02-05T20:52:51+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2026-02-03T06:56:32+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2026-01-12T16:46:44+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2026-01-09T03:42:21+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Medical Informatics and Decision Making","date":"2026-01-09T03:35:52+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
