The study you linked says that for a certain measure, it works better according to a grand total of two studies they looked at. For the rest, the conclusion was that AA performed as well as other interventions. It's also a review study, which can sometimes be helpful, but often cannot draw clear conclusions due to the studies being reviewed not necessarily measuring the same parameters. They also rejected about half the papers they found due to apparent bias.

It's certainly not the kind of paper that establishes something as settled science and even at that, it doesn't say what you claim it does.
