Biochemically Verified and Self-reported 7-Day PPA Rates by Treatment
UC
Abbreviations: ADT, adapted therapy; NP, nicotine patch; OR, odds ratio; PPA, point prevalence abstinence; UC, usual care.Urine was collected by study staff at weeks 12, 18, and 26 to confirm 7-day self-reported abstinence from cigarettes via anatabine and anabasine. All but 4 participants who returned at week 12 (335/339), 2 (331/333) at week 18, and 2 (322/324) at week 26 provided urine samples for analysis.Participants in both groups received 7 smoking cessation counseling sessions and an 18-week supply of smoking cessation pharmacotherapy. ADT participants received NP and up to 2 pharmacotherapy adaptations to varenicline and bupropion + NP based on CO-verified smoking status (CO ≥6 ppm) at weeks 2 and 6. UC participants received NP throughout the duration of treatment.Participants lost to follow-up were imputed as individuals who smoke. Missingness was not related to group or baseline covariates.
