DMP: dimethylphosphate; Total DEP: DEP (diethylphosphate) + DETP (diethythiophosphate) + DEDTP (diethyldithiophosphate) values for each woman. Total DAP (dialkylphosphate): DMP + total DEP values for each woman. Metabolite levels were non-creatinine corrected and the analysis adjusted for testing site, maternal education, agricultural occupation of mother and iodine tablet supplementation during the first and third trimesters of pregnancy. a significant at criterion of p ≤ 0.05. b The change in composite score across IQR of organophosphate exposure levels.
