I clicked some of your 'research' links too, OP. Two of them are articles in 'Medical Hypotheses.' As the name suggests, this is a journal specifically intended for debate and speculation around observations and hypotheses which do not have evidence to support them yet. It does not publish the results of studies or clinical trials. These speculations (while sometimes interesting) are certainly not intended to inform public health advice or clinical practice.
Two of the others don't really seem to be about autism at all (though I can't read the full text of the one in Polish
). The paper in Nutrition is more interesting, but the authors note in their conclusion that the study is limited by lack of data about formula use.
I'm not sure you are entirely familiar with how to do a systematic literature review (it's not just doing a keyword search in Pubmed and cherry-picking the results you like the look of) or that you have read and understood the papers you're referencing.
I also have no idea why you'd post this in the Special Needs section, other than to push some anti-formula agenda or try to make mothers feel needlessly guilty.
