Surgical Face Masks: No Statistically Significant Benefit Against COVID-19. Danish Study in Annals of Internal Medicine 18 November 2020
The much-vaunted Danish mask study was finally published today in the prestigious Annals of Internal Medicine. Now we know why three medical journals were so averse to publishing its findings. The study completely obliterates the cultish devotion to masks. The results of this massive real-life controlled experiment show that the group that wore surgical masks in April experienced a 0.38% lower infection rate than the control group that did not wear masks. That is about one-third of one percent, which is so low that it could just be statistically random variances that demonstrate no definitive efficacy even to that infinitesimal level.
