Efficacy
Statistical methods / analysis
Between-group differences in the primary outcome at 3 months will be assessed using log-binomial regression. Secondary outcomes measured to follow-up cessation will be assessed using mixed-effects models with group and stage (treatment/follow-up) (main effects and interaction) as fixed effects and HCW as random effect. Time-to-ARI and to LRI analyses will use the log-rank test.
