NOTE: Mixed effect models were used to calculate the coefficients (95% CI) of the predictors.

↵* The exposure coefficient is expressed as pre-exposure = 0 and post-exposure = 1. The smoking coefficient is expressed as the change per 100 μg/g creatinine incremental change in cotinine level.

↵† Multivariate models with interaction term are adjusted for age.
