  1. NHANES National Health and Nutrition Examination Survey, CI Confidence interval; Total means continuous chemical variable. Multivariable linear regression was conducted and regression coefficients (β) were calculated while comparing the second, third and fourth quartiles of each chemical with reference to the first exposure quartile (N = 2372). Models were adjusted for age, gender, race, educational levels, family income-to-poverty ratio, caloric intake, serum cotinine, and log-transformed creatinine
