From: Prenatal exposure to heavy metal mixtures and anthropometric birth outcomes: a cross-sectional study
Univariate exposure–response models of anthropometric measures as function selected log-transformed IQR standardized metals (creatinine corrected). Weight (n = 975), length (n = 887), and head circumference (n = 975) are Z-standardized. The independently tested metal is scaled in each model, while the other metals are fixed at the 50th percentile. The gray area on the charts represents a 95% credible interval. Models are adjusted for parity, maternal age, tobacco exposure during pregnancy, standardized socioeconomic index, recruitment center, and creatinine levels
