Fig. 2. Associations of BKMR mixture with A) progesterone, B) estradiol, C) testosterone in all women, women carrying females, and women carrying males.

BKMR models were fit with 200,000 iterations and 50 knots accounting for educational attainment, age, diet quality, pre-pregnancy body mass index, perceived stress in early pregnancy, lifetime smoking status, parity, race/ethnicity, gestational age at plasma hormone assessment. Data are presented as effect estimates and 95% credible intervals which are interpreted as the association between the mixture at each quantile and gestational hormone compared to when all co-exposures are fixed at the median. Estimate and interval color signifies analytic sample (all women: black; women carrying females: pink; women carrying males: blue). Abbreviations: BKMR, Bayesian Kernel Machine Regression.
