A multivariate logistic regression model (Table 4) showed that when controlling for all other significant factors, the following were found to be predictive of smoking abstinence after 12 weeks of pharmacotherapy: the younger the age, the greater was the likelihood to be abstinent (OR = 0.971, p < 0.0001); those who were married were more likely to be abstinent from smoking (OR = 0.678, p = 0.0029); using bupropion was associated with greater abstinence from smoking (OR = 0.480, p < 0.0001); using a combination of bupropion and nicotine inhaler was also associated with greater abstinence from smoking (OR = 0.328, p < 0.0001); conversely, the higher the FTND score, the greater the likelihood to be a continuing smoker (OR 1.244, p < 0.0001); having any prior quit attempts indicated greater likelihood to be a continuing smoker (OR = 1.812, p = 0.004); being a minority was associated with continued smoking (OR = 1.849, p = 0.0083).
