Study Endpoints
Primary Endpoints
Cumulative Percentage of Participants by Heavy Drinking Rate
up to 12 weeks

Cumulative percentage (%) of subjects reporting heavy drinking by category reflecting the various cut-offs for percentage of days that were heavy drinking days. A "heavy drinking day" was defined as 4 or more alcohol drinks in 1 day for women, and 5 or more alcohol drinks in 1 day for men. The Timeline Follow-Back (TLFB) method (Sobell \& Sobell: Humana Press, 1992) was utilized to collect subjects' daily drinking information (ie, the number of drinks consumed per day per subject which was retrospectively recalled and recorded in a diary).
