But then they say this:
"while cloth masks clearly reduce symptoms, we cannot reject that they have zero or only a small impact on symptomatic SARS-CoV-2 infections"
Not exactly a slam dunk.
The surgical mask effect is certainly interesting, but they couldn't de-correlate the effect from increased social distancing in the intervention arm. Certainly that seems just as likely to make a difference if not more so eh?
So I'm left where I started: Nothing of consequence about cloth masks, and a mild un-corroborated effect from surgical masks in a country that's about as different from the US as I could imagine.
I wouldn't base public policy on that study, that's for sure. I have no problem if people want to wear masks, go for it. But mandates? I have a higher bar than you to infringe on personal freedoms I guess.
