  Your own link has several studies with numbers in the same ballpark as what I cited. Here's the CDC study: https://www.cdc.gov/mmwr/volumes/70/wr/mm7010e3.htm https://www.cdc.gov/mmwr/volumes/70/wr/mm7010e3.htm

    Here's the "2%." https://www.cdc.gov/mmwr/volumes/70/wr/mm7010e3.htm#F1_down https://www.cdc.gov/mmwr/volumes/70/wr/mm7010e3.htm#F1_down It's "percentage point change," which I read as absolute percentage points. It's different from you what said, "masks reduce transmission by all of 2%," but it also looks like a garbage number because you can't average percents like that and get meaningful data, and the result is hard to interpret. If masks drop the growth rate by 2 percentage point, two percentage points from what?
