PRIMARY outcome

Timeframe: Randomization (Week 0) to Week 12

Population: Data unavailable for one placebo participant who did not provide any Timeline Follow Back data (TLFB).

Frequency is assessed as number of binge episodes/time in trial controlling for missing data.

PRIMARY outcome

Timeframe: Randomization (Week 0) to Week 12

Population: Data unavailable for one placebo participant who did not provide any Timeline Follow Back data (TLFB).

Intensity is defined as the number of drinks per binge day scaled by the minimum threshold of a binge episode per gender (4 drinks/day for females; 5 drinks/day for males). Accordingly, if a female consumed 4 drinks in a binge drinking day, the intensity would be 1.0 and a female who consumed 6 drinks in a binge drinking day would have an intensity of 1.5.
