Hmm, that's one explanation, but I'm curious what leads you to believe it's the correct one?

I'm struck by this quote, which I'd be surprised if they could be explained fully by the distraction-reduction mentioned:

> "Evaluation of symptoms on the Parent Global Impressions found that the treatment group at the end of part 2 improved more than the placebo group in part 1 on nearly all symptoms, with statistically significant improvements in GI, receptive language, and average of all symptoms. There were also marginally significant improvements in tantrums, stimming/perseveration, and cognition."
