Dane here, so I've read the study.
One of the important aspects here is of course the sample size, the timing of the study (during a downward trend in Denmark) and more importantly, it doesn't tell us if it protects others (which other research points to).
- comicjk 6y agoThis is the key fact. Only 2% of the subjects tested antibody-positive at the end of the study (low enough that it's near the false-positive rate of the home antibody tests). The mask group had fewer cases (by PCR, they had zero). But the numbers are too small to say. If you ran the study in the US in the same time period, you would have had a better shot.
