It's a good thing then that it's a compendium of sources, including peer reviewed papers from medical journals, huh?Wikipedia is not a peer reviewed paper from a medical journal, and studies other than very recent hysteria driven anecdotes do not claim efficacy of cloth masks.
In addition to checking those sources out, perhaps read my point on how it wouldn't matter in the slightest if every bit of data we had on cloth masks was from 2020.
