  1. All models are adjusted for maternal age, maternal education, child’s gender, exposure to second-hand smoke, HOME score, maternal Raven score, and child hematocrit levels. Models use age-adjusted BSID-III scores
  2. All exposures are included in the models simultaneously
  3. Ln natural log, SE standard error, As arsenic, Mn manganese, Pb lead
