Participation in AA or other support groups (eg. SMART/Rational Recovery) is associated with substantially increased rates of continuous abstinence at the 1, 3 and 5 year marks after quitting, although there may be some self-selection bias going on there (participation rates being higher among the more motivated and so on).
It's been shown, as much as is possible, that that's all selection bias. People rarely fall off the wagon and then keep going to meetings.
AA's rules around anonymity and consent make it conveniently impossible to run good studies, so they are able to (rightly, for the most part) write off any study that runs against them, but are also unable to show any positive findings that don't fall prey to very obvious problems.

I have a significant number of acquaintances who did exactly that, myself included, but I am not going to make the claim that my personal experience means anything statistically.

If that is the case, feel free to provide some sort of citation to back up your claim.
In Project MATCH [1] we learn that "twelve-step" (AA), cognitive behavioral therapy, and motivational enhancement therapy all have very similar results across a large number of measures.
We also find that CBT performs equivalently to "brief opportunistic intervention" (which goes under a variety of names, but takes a single 5-minute meeting), which is the minimum amount of treatment that we're ethically allowed to give alcoholics.
So it may work better than nothing (can't really study that), but there are much lower-touch methods that give equivalent results.

Why the focus on high-touch/low-touch? It doesn't cost anyone anything except for those who attend, and even those who do aren't obligated to spend anything. It does take up some time, but it is time that I enjoy spending.
I have undergone both CBT and yes, have attended AA. The former did not do much for me, the latter did. AA as practiced in my area is strongly remniscent of CBT, only with additional social support, which is helpful for recovering alcoholics who have likely either alienated most people or who have built social networks focused around substance abuse.
If you were to say that addiction is complicated and the right course of treatment is difficult to determine and efficacy is hard to measure, I certainly would agree.
It is a high-touch treatment that performs as well as a 5 minute intervention, despite constant claims that it is better. In the post I originally replied to, you implied that you were comparing it to other methods rather than nothing, although it wasn't terribly clear.

The oft-claimed improvement of AA over other methods messes up our views on addiction, as well as the justice system for addicts. Our refusal to use drugs to fight addiction even though the science is quite clear stems from full-abstinence organizations, largely led by AA.
A couple of days ago, I stepped off my back porch wrong and broke my ankle pretty badly. I was in a lot of pain, and I definitely needed to go to the hospital. A part of me was actually quite excited at the possibility of obtaining a "legitimate" supply of opiate painkillers. Luckily, I called a friend from AA and took his much more reasonable advice not to take the chance. Once I'd made that decision I realized that I'd been greatly exaggerating the pain to myself, and that it was nothing OTC painkillers couldn't handle.
Scary stuff, right? I had come up with a way to convince myself that it'd be ok to take score some drugs, which could very easily have sent me off into a relapse. It's when things like that happen that you need to listen to a "higher power": someone who isn't having your crazy addict thoughts and can assess your behavior rationally and objectively.
Since I'm laid up, AA people have been helping me get groceries, rides to meetings, and just stopping by to say hi. I can't really see a recovery professional doing that.
