NOTE: Values represent weighted means (95% CI) for continuous variables, or weighted percentage distribution (95% CI) of these variables within tobacco use categories for categorical variables. ANOVA was used to compare study group characteristics for continuous variables and Pearson χ2 or Fisher's exact test for categorical variables.
