A very good thread on that Danish mask paper

I mean, there's some possibility that none of these tests would pick up someone who got infected right at the end of the study period, but surely you'd expect it to get most of them?

Actually, I'm thinking carefully about this and I don't think it matters. The study is randomized, so as long as they met their recruitment target and expected power the argument about it being too short makes no sense imo
Thanks. Twitter will use this to make your timeline better. UndoUndo

You would. Just not clear what % may have been infected already, still shedding RNA but not yet having developed a detectable Ab response. But as you say, it was randomised.

Yeh, I don't think the criticism makes sense tbh. If it was powered sufficiently, and the endpoint (AB/PCR+) is reasonable, then saying it's too short is wrong
