Note: GM, geometric mean; GSD, geometric standard deviation; Pesticide-Paper ID is a unique identifier assigned to each pesticide active ingredient-publication combination; Statistic ID is a unique identifier assigned to each GM. These IDs were used in the mixed-effects modeling [see “Appendix 1. Statistical (SAS) Code for Meta-Regression Models for Pesticide Exposure Pathways” in Supplemental Material]. aDistance categories were assigned the midpoint of the category. bGolla et al. (2012) measured atrazine at homes of varying distances to fields across two seasons.
