> given that a large Danish study says that masks doesn't reduce your risk of infection in a significant way That’s not what this study says. What the study actually says is that they found wildly huge odds ratios in their confidence interval. The only “conclusion” that can be drawn from this is that the study is inconclusive. To explain further: to positively conclude that there’s no benefit to mask wearing, the study would have had to produce a small confidence interval around zero effect. In reality, its 95% confidence interval is between 46% reduction to a 23% increase in infection. Any number between these bounds is compatible with the study results. That’s all over the place, and doesn’t allow any conclusion.
