DLM models for cord blood changes of 17α-OH-pregnenolone and androstenedione with weekly mean exposures of respectively PM2.5 or black carbon during pregnancy. Distributed lag models to estimate the week-specific associations of the weekly IQR (interquartile range) increments of gestational exposure to the air pollutants, PM2.5 (n = 397) and black carbon (BC n = 378), with cord blood levels of respectively (A) 17α-hydroxypregnenolone, indicated as 17-OH-pregnenolone, and (B) androstenedione. Whiskers around the point estimates represent the confidence intervals (CI 0.95) of the week-specific estimates. Models are adjusted for sex of the child, birth weight, smoking during pregnancy, gestational age, age of the mother, the season of delivery, and maternal education
