↵† Adjusted for age, gender, social grade and time to the first cigarette of the day.
↵‡ Those reporting smoking reduction compared with those reporting that they were not reducing their cigarette consumption.
↵§ Those reporting smoking reduction with NRT versus those reducing their smoking without NRT.
↵¶ Those reporting temporary abstinence with NRT versus not using NRT for temporary abstinence.
NRT, nicotine replacement therapy; OR, odds ratio calculated from logistic regression; SR, smoking reduction; TA, temporary abstinence.
