Details

We follow Mannino rt al. (2003) in constructing a dataset that includes children aged 4-16 years old for whom both serum cotinine levels and blood lead levels were measured in the Third National Health and Nutrition Examination Survey (NHANES III), along with the following variables: race/ethnicity, age, sex, poverty income ratio, education level of the reference adult, family size, number of rooms in the house, and year the house was constructed. The biomarker cotinine is a metabolite of nicotine and an indicator of second-hand smoke exposure. Treatment status is 1 if cotinine level is between 0.563-14.9 ng/ml and 0 otherwise. All continuous/ordinal variables are standardized by subtracting the mean and divided by 2 standard deviations so that they are more comparable to binary covariates (Gelman 2008).
