Yeah, there is a TON of contradictory information out there on it. I started getting interested in it in recent years because I have a good friend who is very involved in Autism Speaks and the research/advocacy work they do, so she always is up to date on what the recent research is saying. All the publications I've read have been here and there just out of interest, not for a research paper or anything, so I didn't save them. But I can try to find some of them this weekend and send them to you.
