结局指标
主要结局
7-day point prevalence abstinence assessed in the telephone follow-up survey
时间窗: 12 months after baseline survey
Self-reported 7-day point prevalence abstinence (PPA) is a validated, commonly used measure of smoking cessation. Subjects who reports no smoking in the preceding 7 days at the time of 12-month survey in the follow-up are regarded as quitters. This measure has serval advantages compared to continuous abstinence. First, it can include smokers who take delayed action and quit. It also allows relapses to occur in the follow up period, without classifying smokers as permanent failure. Third, it does not rely on recall of past events happened long ago.
