TL;DR: Threshold values for sperm concentration, motility, and morphology can be used to classify men as subfertile, of indeterminate fertility, or fertile and none of the measures are diagnostic of infertility.
Journal ArticleDOI

TL;DR: It is concluded that in both Bangladesh and the United States, some children are at risk for Mn-induced neurotoxicity.
Journal ArticleDOI
Characterization of Weighted Quantile Sum Regression for Highly Correlated Data in a Risk Analysis Setting.
TL;DR: A weighted quantile sum (WQS) approach to estimating a body burden index, which identifies “bad actors” in a set of highly correlated environmental chemicals, and demonstrates the improvement in accuracy this method provides over traditional ordinary regression and shrinkage methods.
Journal ArticleDOI
