I have a theory about it.
The study was done in Denmark, and the overwhelming majority of circumsized men/boys are foreigners. Most of these would be Africans or Arabs. It's been shown that women with darker skin give birth more often to autistic children as they can't get the necessary amounts of vitamin D that far up north without taking supplements. Somalis in Sweden, for example, have taken to calling autism the "Swedish disease". I think it may actually be what is showing in this study.
Just a theory, of course.
