  1. aOdds ratio (OR) and 95 % CI corresponding to IQR change in adjusted EPDS score (IQR = 7.3)
  2. bOR and 95 % CI corresponding to 1 unit change of ln(maternal blood lead ug/dl), which corresponds to a 2.7 fold increase in second trimester maternal blood lead level
  3. cOR and 95 % CI corresponding to per 1 unit change per 10 ug/g change in metal measurement
