:I agree that your wording is better.  However, I'm concerned that including this at all gives too much weight to a single study.  To make a claim about the health effects of pesticides, the policy that should give us guidance is Wikipedia:Identifying reliable sources (medicine).  In this case, a single primary source is insufficient to meet this criteria.  If there are reliable secondary sources (such as review articles published in a scientific journal) that support the connection between pesticides and autism, then I think we could add content based on that.  In the absence of that being available, I think it is best to wait for researchers to follow up on this study before including it in Wikipedia.
