  1. Model Summaries are for Children with B-Pbs lower than 10 μg/dL, Overall and Stratified by Race/Ethnicitya.
  2. aFor All Races, model includes blood lead concentration, gender, mother’s education, low-income, very low birth weight/early preterm, child’s age at time of B-Pb, ISAT vs. Iowa, and race (black vs. white and Hispanic vs. white).
  3. bFor individual races, model includes blood lead concentration, gender, mother’s education, low-income, very low birth weight/preterm, child’s age at time of B-Pb, ISAT vs. Iowa.
