Strange, right? Take a look at figure 4 here: https://jamanetwork.com/journals/jamapsychiatry/fullarticle/...

This is as in the abstract:

1. drinks/day declined in both groups and somewhat more in the treatment group but wasn't statistically significant 2. number of drinks/day basically wasn't different at all 3. drinks/drinking day didn't change in the placebo group but did decline in the treatment group

(These are all actually regression coefficients computed on non-random samples but nevermind.) Somehow it seems like what's happening is that 3 rises to statistical significance even though 1 doesn't.
