Wow, based on that study masks are way less effective than I thought. They couldn't find any significant impact on COVID from cloth masks, even though the study was quite large. And increasing usage of surgical masks by 30 pp reduced the number of cases by 10% - which is pretty good, but still not nearly the numbers I've seen floating around, especially when considering that villages with masks also had increased social distancing.
Not to say that the mask mandates were entirely useless, at least for indoors (outdoor masking seems kind of pointless), but it doesn't seem like they are as significant as we thought.
