The study implies antibiotics but I don't see that data. Am I missing it? There is discussion of data connecting future diagnosis with early antibiotics, but nothing that clearly shows that is causal.
I think there is a discussion to be had about the possibility that ADHD and autism increase the risk of other conditions that may then require more antibiotics. I'd like to see a more detailed study trying to tease correlation/causation out before making a statement like `The findings suggest links to immunodysregulation and metabolism, compounded by ... antibiotics`
