^aModel 1: logistic regression adjusted for study matching factors (child sex, month and year of birth).

^bModel 2: $\text{Model}1+\text{maternal}\text{age}$ (continuous), maternal race/ethnicity (non-Hispanic white, Asian, Black/Pacific Islander/or other, Hispanic, or Missing), maternal weight at time of sample collection (quartiles), parity (multi- vs. primiparous), and maternal education ($<\text{high}\text{school}$, high school, college, graduate).

^cp-Value for BFR coefficient from adjusted model 2.

^dSum of all congeners shown in this table (e.g., those with at least 55% of study population with values $>\text{LOD}$).
