Sure, but if you had a 30-day PCR, IgG and IgM surely you wouldn't expect to have missed many cases?

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
