All three links don't seem to conclusively support your comment and AA continues to be controversial for many reasons (e.g. adopting "alcoholic" as your identity). Quoting link #2:

"Mostly it [the new review] looks like studies of either sending people to AA or frequent counseling, and that yields similar results to other kinds of alcohol use disorder psychotherapies.
