  1. aPrenatal triclosan concentrations derived from the mean of the 16-week and 26-week urinary triclosan concentrations (N = 220). Early childhood triclosan concentrations derived from the mean from 1 to 5 year annual urinary triclosan concentrations (N = 212). N = 218 for 8-year urinary triclosan concentrations
  2. bUnexposed: < 0.015 ng/ml serum cotinine was classified as unexposed, Secondhand Smoke: ≤ 3.0 ng/ml serum cotinine, Active Smoking: > 3.0 ng/ml serum cotinine
