A previous citation of mine, "Facemasks in the COVID-19 era: A health hypothesis" has been officially retracted for a few reasons, none of which pertain to the cited studies. It doesn't change the research, some of which which is aggregated above as well. I've had a thought to actually critically evaluating the paper myself, because the references are still valid, and the argumentation is clear. This does appear as though sociopolitical pressure was used to bring the journal to heel. The journal talks about redesigning its "editorial and review workflow" over it. I've listed many data on this site documenting masks (and if you want more, I've got a bunch of unqualified URLs in the source for this page), so it's evident that this move is not coming out of a clear scientific basis. There's another list of resources after the main article content / video embeds here.
