ACT = acceptance and commitment therapy; CBT = cognitive behavioral therapy; OR= odds ratio; PPA = point prevalence abstinence
aOdds ratios are adjusted for the five factors used in stratified randomization: stratified by gender, quit attempts in the past 12 months (yes/no), binge alcohol use (yes/no), positive screen for anxiety or depression symptoms (yes/no), and number of cigarettes per day (less than a pack vs. a pack or more).
bMissing equals smoking was specified a priori as the primary outcome as recommended by the Russell Standard.
cComplete case analyses included n = 173 ACT and n = 176 CBT participants.
