Table 4.

The left side contains results from the zero-drink hurdle model and the right side contains results from the <=3 drink and <= 4 drink hurdle model fit to post-treatment period data (weeks 17-26). ACA=acamprosate, NTX=naltrexone, Prior No. Drink = average number of drinks per day for the month prior to the required abstinence period.
