Note. OR = odds ratio; CI = confidence interval; HSI = heaviness of smoking index. Analyses were adjusted for race/ethnicity, gender, age group, education, income, HSI, intention to quit, time in sample, and instrument change. All correlates were measured prior to the assessment of the outcome. Generalized estimating equation modeling approach was used; N indicates number of unique individuals within rows (therefore, sum of N across rows within variables will not equal total N inasmuch as individuals are present in multiple levels of a variable at different timepoints); row percentages are based on corresponding row N.
aAmong those who smoked menthol cigarettes at previous wave, 8% switched to nonmenthol.
bAmong those who smoked nonmenthol cigarettes at previous wave, 3% switched to menthol.
cAmong those who did not switch across cigarette types between waves, 12% switched within type; additionally adjusted for type.
