Not perfect, nor confirmatory, but a good enough study to modulate the probability of a large self-efficacy from masks. Study powered to a 50% RRR, correctly concluded that it does not reduce infection by 50%. A negative study is negative only for the effect size it was powered https://t.co/aDPxRoIuqS
