1 All participants at Month 6 includes 41.4% (n = 577) predominant fruit/other flavor users, 52.5% (n = 732) predominant mint flavor users, 4.3% (n = 60) SP nonusers, and 1.7% (n = 24) participants who used equal amounts of fruit/other and mint flavors.
2 Type of cigarette smoked at Month 6 was based on responses provided at Baseline; thus, results are the same for both timepoints. Statistical comparison reflects difference in type of cigarette smoked at Baseline between predominant fruit/other and predominant mint users. Type of cigarette smoked was not assessed at Month 6.
3 Smoking frequency presented for those who were daily or nondaily smokers at Month 6; results at Month 6 do not include those who had quit smoking.
4 Current smoking was defined as those who had smoked daily or nondaily in the past 30 days at the respective timepoint.
5 Continuous variables compared using Student’s unpaired t-tests; categorial variables were compared using chi-square tests. Baseline versus Month 6: p < 0.001 for all comparisons.
