The metaanalysis you link does not show the effectiveness of ABA therapy. The studies included are without a control group. If the post therapy IQ is higher than the pre-therapy IQ, that's only to be expected, as the children are older and have matured. The therapy is enormously expensive (several years of many hours per week!) and as you correctly say, many if not most kids below 4 are on the waiting list. It would be the easiest thing in the world to do a really large randomized controlled study with a waiting list control group. If correctly done experimental studies according the usual medical standards are rare among the published material on ABA, and "naturalistic" studies abound, maybe most of the methodologically better studies that were done went into the drawer as the results were not to the liking of the therapist lobby.

The one thing that may help parents of very young children with highly concerning autism symptoms is a referral to genetics. Most of the time, genetics won’t find anything, but if parents are “lucky” enough to draw a genetic diagnosis, it cuts the red tape. That wasn’t possible when your son was young, but these days a genetic screening is cheap and easy enough that insurance will usually pay for it.
