That Danish study only had about 120 people infected overall (and over 1000 drop out of the study midway). So it's not really N=6000, it's N=120, which is tiny

That Danish study only had about 120 people infected overall (and over 1000 drop out of the study midway). So it's not really N=6000, it's N=120, which is tiny. The evidence from RCTs is way too preliminary to draw any conclusions. The best evidence so far is from studies that directly measure whether a mask can block aerosols, and those results are very compelling. We do need more and larger RCTs though.
