STAND (Smoking Tobacco and Drinking) intervention: Tobacco + Alcohol content; TSP (Tobacco Status Project) intervention: Tobacco only content
ITT (intent to treat) sample size: STAND N=85, TSP=94
FTCD: Fagerstrom Test of Cigarette Dependence, HED: heavy episodic drinking, AUDIT-C: Alcohol Use Disorder Identification Test – Concise
SD: standard deviation, IQR: interquartile range
Effect estimates are odds ratios for dichotomous outcomes unless otherwise noted and B for continuous outcomes
Estimate adjusts for baseline differences in intervention arms
Adjusted for number of heavy episodic drinking days at baseline
