This edit changed almost none of the content of the page, just found citations to (maybe) support whatever it already said. It was done by PraiseVivec, who has over 3000 edits. They are passionate about "Incredibly specific subjects [they] literally knew nothing about 5 minutes ago" and are "particularly proud" of this page.
I'm 100% sure that Wikipedia editors of contentious topics know what they want to write and then just go to Google Scholar to source their idea. Heaps of the references are terrible.
One of the weaknesses of Wikipedia's model is sources aren't weighted. It's either cited or uncited, and Cochrane reviews don't look better than web citations.
