Exposure-response functions ¹ associating each of the five main exposures (Set 1²) and a second exposure fixed at various quantiles with the Delis–Kaplan Executive Function System inhibition scaled scores: (a) Design Fluency total correct scaled scores and (b) Color–Word Interference completion time scaled score, while the remaining exposures are assigned to their median value among adolescents in the main analysis group. ¹ Exposures have been log2-transformed and models have been adjusted for child race, sex, age at exam, year of birth, and HOME score; maternal marital status at child’s birth, IQ, seafood consumption during pregnancy, and smoking during pregnancy; maternal and paternal education and annual household income at child’s birth; and study examiner. ² Set 1: complete outcome, covariate and exposure data for DDE, HCB, ΣPCB₄, Pb and Mn, n = 373.Abbreviations: DDE: dichlorodiphenyldichloroethylene; HCB: hexachlorobenzene; ΣPCB₄: Sum of 4 PCB congeners (118, 138, 153, 180); Pb: lead; Mn: manganese.
