  • * Adjusted for age, sex, race, poverty income ratio, BMI, cigarette smoking, serum cotinine, alcohol consumption, and exercise.

  • The median serum concentration in each category is displayed.

  • P trend was calculated without a quadratic term in the model, while P quadratic was calculated including the linear term.
