Mediation analysis of the estimated effect (95% confidence intervals) of maternal serum PFASs levels and newborn outcomes by maternal serum thyroid hormones for all infants/by sex. The figure presents maternal serum thyroid hormones as a mediator, the estimate of the indirect effect (IE), the estimate of the direct effect (DE), and the proportion of mediation (IE/IE + DE). The mediation model was adjusted for maternal age at delivery, level of education, smoking status, occupation, pre-pregnancy body mass index (BMI), gestational weight gain, family income, parity, method of delivery, living area, and the sex of the infant.
