Indeed the recent Damask-19 research in Denmark found no particular evidence for the efficacy of masks.
That's not the case. For one thing, that study only looked at whether masks protected the wearer, while the main reason for wearing masks is to prevent the wearer infecting other people. And the sample size was too small, which meant that the results weren't statistically significant (which means that you don't know with any sort of statistical certainty whether the results are accurate, and not, as people often assume, that there wasn't any significant difference between mask an non-mask wearers).
