Thanks for the counter vote, it functioned for visibility, its purpose already being served since you replied - removed my own vote too, didn't expect others would top it up.
The study you put here states:
Further research is needed to inform the widespread use of cloth masks globally
And this is the part most people tend to gloss over unfortunately. MORE research seems like a pain and a waste of time to casual readers. So I think I'm talking to myself as much as you that we need to make very clear that one study is not = the answer, in any scenario, and where possible, use meta-analyses rather than individual studies
One thing I like to do to keep my personal views in check is to read carefully the 'discussion' section in publications, probably most have this but not all. This is where they often highlight the flaws and inconsistencies in their methodologies, and sometimes it can be the difference between me having a conclusion or dumping the idea entirely.
