Circulating Vascular Endothelial Growth Factor and Soluble fms-Like Tyrosine Kinase-1 as Biomarkers for Endometrial Remodeling Across the Menstrual Cycle
·doi:10.1097/aog.0000000000004171

OBJECTIVE: To characterize variation in circulating vascular endothelial growth factor (VEGF) and its receptor, soluble fms-like tyrosine kinase-1 (sFLT-1), across the menstrual cycle in normal ovulating women in relation to reproductive ho…

Effects of over-the-counter analgesic use on reproductive hormones and ovulation in healthy, premenopausal women
·doi:10.1093/humrep/dev099

STUDY QUESTION: Does use of commonly used over-the-counter (OTC) pain medication affect reproductive hormones and ovulatory function in premenopausal women? SUMMARY ANSWER: Few associations were found between analgesic medication use and re…

Multivariate normally distributed biomarkers subject to limits of detection and receiver operating characteristic curve inference
Academic radiology ·doi:10.1016/j.acra.2013.04.001

RATIONALE AND OBJECTIVES: Biomarkers are of ever-increasing importance to clinical practice and epidemiologic research. Multiple biomarkers are often measured per patient. Measurement of true biomarker levels is limited by laboratory precis…

Assessing Chemical Mixtures and Human Health: Use of Bayesian Belief Net Analysis
Journal of environmental protection ·doi:10.4236/jep.2012.36056

BACKGROUND: Despite humans being exposed to complex chemical mixtures, much of the available research continues to focus on a single compound or metabolite or a select subgroup of compounds inconsistent with the nature of human exposure. Un…

ROC curve inference for best linear combination of two biomarkers subject to limits of detection
Biometrical journal. Biometrische Zeitschrift ·doi:10.1002/bimj.201000083

The receiver operating characteristic (ROC) curve is a tool commonly used to evaluate biomarker utility in clinical diagnosis of disease. Often, multiple biomarkers are developed to evaluate the discrimination for the same outcome. Levels o…

Youden Index and optimal cut-point estimated from observations affected by a lower limit of detection
Biometrical journal. Biometrische Zeitschrift ·doi:10.1002/bimj.200710415

The receiver operating characteristic (ROC) curve is used to evaluate a biomarker's ability for classifying disease status. The Youden Index (J), the maximum potential effectiveness of a biomarker, is a common summary measure of the ROC cur…

Receiver operating characteristic curve inference from a sample with a limit of detection
American journal of epidemiology ·doi:10.1093/aje/kwk011

The receiver operating characteristic curve is a commonly used tool for evaluating biomarker usefulness in clinical diagnosis of disease. Frequently, biomarkers being assessed have immeasurable or unreportable samples below some limit of de…
