During March 1–December 31, 2020, state-issued mask mandates applied in 2,313 (73.6%) of the 3,142 U.S. counties. Mask mandates were associated with a 0.5 percentage point decrease (p = 0.02) in daily COVID-19 case growth rates 1–20 days after implementation and decreases of 1.1, 1.5, 1.7, and 1.8 percentage points 21–40, 41–60, 61–80, and 81–100 days, respectively, after implementation (p<0.01 for all) (Table 1) (Figure). Mask mandates were associated with a 0.7 percentage point decrease (p = 0.03) in daily COVID-19 death growth rates 1–20 days after implementation and decreases of 1.0, 1.4, 1.6, and 1.9 percentage points 21–40, 41–60, 61–80, and 81–100 days, respectively, after implementation (p<0.01 for all). Daily case and death growth rates before implementation of mask mandates were not statistically different from the reference period.
No, the CDC specifically said masks dont do shit:
Cdc:
That's great info, do you have a link ?
cdc (dot) gov/mmwr/volumes/70/wr/pdfs/mm7010e3-H.pdf
So these shithole labor unions are actively spreading LIES about what the CDC happens to be saying today.
It's not enough that the CDC is reverses itself regularly and is completely unreliable.
Doesn’t that imply they helped?
It does, but like less than 2% I guess. Until the last sentence, which makes no sense. Probably have to read the complete study to see.
No. Specifically that they did nothing. When any effect is less than the margin of error, you have no effect.
No, as it is within the margin of error it cannot be supported.
