... It doesn’t seem like his statement was a misrepresentation based on the paper’s conclusions/results. On the other hand, your phrasing “merely found that poorly-washed cloth masks weren't as good as surgical masks” does feel like a misrepresentation as it implies that ...

Zeynep’s tweet reads more like what this study is not rather than implying anything specific. RP doesn’t imply but *states* that following advice regarding masks is submission. Both the abstract and added comments from the authors clearly state the control is PPE mask wearers

What part of RP’s tweet do you think is misrepresentation? (That’s a sincere question.) The “submission” part is clearly his commentary on the situation and not scientific in any sense. To the best I can tell, everything his says is accurate, and not distorted. It is the only ...

... RCT on cloth masks. The paper does say 97% of particles pass through, and that infection is 12x(!) higher than with surgical masks and 3x higher than the control for ILI, and for lab confirmed virus cloth masks have 1.65x that of surgical masks and 1.35x that of the ...

... much higher rate of infection in the cloth mask arm could be interpreted as harm caused by cloth masks, efficacy of medical masks, or most likely a combination of both.” Seriously, what specifically is the misrepresentation?

From the conclusion: "It is also unknown whether the rates of infection observed in the cloth mask arm are the same or higher than in HCWs who do not wear a mask, as almost all participants in the control arm used a mask."

Plus it's not a study of source control, which is why the primary reason we recommend masking in the community, though increasing evidence it is also protective.

It’s true that it’s not a study of source control, but then again none of the evidence *for* mask wearing (much less cloth mask wearing) is a source control RCT either. It’s all either 1. We blew into the fabric mask and measured how much was filtered. Which tells us next ...
