Note: n = sample size, slope = regression coefficient for MeHg, SE = standard error of slope, Lower = 2.5% lower confidence bound for slope, Upper = 97.5% upper confidence bound for slope. All outcomes were regressed on child’s 7 year hair MeHg (ppm) and the following covariates: mother’s age at delivery, maternal KBIT-2 matrices, prenatal MeHg from maternal hair at delivery (ppm), n-6:n-3 ratio, child’s age at 7 year testing, child sex (female = 1), family status at 7 years (both parents with child = 1), Hollingshead SES at 7 years.
