Outcome
- Type
- SECONDARY
- Title
- Self-reported Continuous Tobacco Abstinence

Continued cessation of cigarette use was analyzed by comparing 3- and 6-month 7-day point prevalence in smoking cessation.~If participants withdrew or did not answer the survey, they were marked as having recently smoked. Thus, participants needed to complete the survey and indicate that they had stopped tobacco use at both 3- and 6-month timepoints to be identified as having continuous cessation.
- Time frame
- At 3months and 6 months
- Population
If participants withdrew or did not answer the survey at the specified timepoint, they were marked as having recently smoked Analysis only includes participants having a result for the 6-month timepoint
