a
Age entered into model as a continuous variable. Reference category for race/ethnicity is “other” race; for education, less than high school; for income, less than $20,000.
b
Excluded because model included recent quitters (those who were no longer current smokers) at follow-up. This survey item was only asked for respondents at each wave who reported being current smokers.
