Supplementary tables and figures for Sex Differences in Association of Mixed Exposure to Five Blood Heavy Metals and Osteoporosis: Evidence from NHANES

Supplementary Table 1 compares basic characteristics by sex. Supplementary Table 2 presents the 95%CI and P-value of the WQS regression model for the analysis of the association between blood heavy metals and osteoporosis.

Supplementary Table 3 provides the posterior inclusion probabilities (PIPs) generated by the Bayesian kernel machine regression (BKMR) model. Supplementary Figure 1 provides the association (95% CI) between single metal exposure and osteoporosis when other metals were fixed at specific quantiles (25th, 50th, and 75th quantiles). Supplementary Figure 2 provides the interaction of the two heavy metals when the second heavy metal was fixed at the 10th, 50th, and 90th percentiles, respectively, using the BKMR bivariate expose-response function.
