Joint effect (95% CI) of the log-transformed dioxin and PCB mixture on the Bayley Scales of Infant Development second edition (BSID-II) (a) Mental Developmental Index (MDI) and (b) Psychomotor Developmental Index (PDI) by Bayesian kernel machine regression (BKMR) model in the Hokkaido Study Small Cohort of the Hokkaido Study on Environment and Children’s Health (n = 259). The overall effect of prenatal exposure to dioxins and PCBs on infant neurodevelopment was plotted by comparing the impact when all dioxins and DL-PCBs are at a particular percentile with the effect when all of the congeners are at their medians. Models were adjusted for maternal age, education, household income, work status during pregnancy, smoking status during pregnancy, and fish intake during pregnancy (inshore and deep-sea fish).
