"Mask policy" - what a government organization (DOH, city council, what have you) states as its recommended behavior, action, enforcement practices.
And has _absolutely nothing to do with_ epidemiological studies on communities. Nothing. Whatsoever.
Policy: 'you should do X'
Epidemiological study: a controlled investigation into what happens when people do X, when they don't, including how many do, how many don't, and all the circumstances surrounding it.
The first three articles:
1. Meta analysis of mask usage
2. "''A Danish randomized controlled trial with 6000 participants, published in the Annals of Internal...."''
3. """large randomized controlled trial with close to 8000 participants"""
You clearly didn't click on the first two articles like you said you did.
You're a liar and a fascist.
I'm done here.
You mean epidemiological studies on communities?
Ok....
Masks may or may not work as a stop for particles but do they stop spread on a community level?
