PRIMARY outcome

Timeframe: 3 months

Population: Three-month abstinence rates among participants who received NRT were compared with those who received varenicline. Although some participants stopped taking the pharmacotherapy, or switched from varenicline to NRT, for the analysis , they were kept in their initial group. Because treatment assignment was not random, inverse probability of treatment weighting (IPTW) adjustment was performed. A propensity score was estimated as the probability of receiving varenicline, given measured covariates

SECONDARY outcome

Timeframe: 12 months

Population: Abstinence rates among participants who received NRT were compared with those who received varenicline. Although some participants stopped taking the pharmacotherapy, or switched from varenicline to NRT, for the analysis , they were kept in their initial group. Because treatment assignment was not random, inverse probability of treatment weighting (IPTW) adjustment was performed. A propensity score was estimated as the probability of receiving varenicline, given measured covariates
