We never had solid studies on community use (most good studies focused on ingress rather than community use, see difference here https://www.theatlantic.com/health/archive/2020/04/dont-wear-mask-yourself/610336/ …) but even what studies we have (many with low compliance/not good controls) supported some benefits for reducing transmission.

I'll just say that every week there is more evidence, new papers and new case studies. They all point in the same direction. Final paper will be even stronger. I'm a pragmatist; if there was some reason to think otherwise, I'd be very open about it. Cheers!

I feel you're trying to say I misunderstood (twice) or I am not clear on the goals. I didn't challenge those. You're defining a narrow question and drawing a correlation. I offered papers I (not me, a clinical Prof) found in a cursory look and still feel relevant. That's it.
