From: Prenatal exposure to heavy metal mixtures and anthropometric birth outcomes: a cross-sectional study
The individual exposure contributed to the overall effect of the metal mixture on z-standardized anthropometric measures. Weight (n = 975), length (n = 887), and head circumference (n = 975) are Z-standardized, while all metals (creatinine corrected) are log-transformed and IQR standardized. Using BKMR models, the individual contribution is indicated by the change in anthropometric estimates when exposure is at the 25th compared to the 75th percentile, while all the metals are fixed at either 25th, 50th, or 75th percentile (as indicated by Quantile fixed). 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
