Note. CI = confidence interval; OR = odds ratio. Table displays percentage reporting cessation and ORs (95% CIs) for cessation in the untailored and tailored intervention arms relative to the control arm at each time point. The first model with available data at each time point excludes those lost to follow-up. The second model at each time point assumes those lost to follow-up did not quit (i.e., continued smoking waterpipe tobacco).
