smoking abstinence
Periodo de tiempo: 6-months
The dependent variables of primary interest were measured at 26 weeks and included: (1) bio-chemically confirmed 7-day point prevalence abstinence; and (2) continuous abstinence since TQD. Participants who were not available for follow-up were considered smokers. At the 26 week follow-up, all patients who reported being abstinent from smoking had their smoking status confirmed by measurement of a CO sample. If any CO was >10 ppm, the subject was considered a smoker.
