You might want to read the whole article before you use it to say the case is closed. The article admits they were only to ‘observe’ after the fact, no blind study and no actual math/science to look at the others factors in each observation. Additionally, they kept going back to ‘multi-layer’ masks. Don’t know about you, but most of the gators and masks I see are not multi-layer. There was a Dutch study that showed no statistically significant benefit. Lots of discussion about the study, but it at least attempted to perform an actual experiment vice drawing conclusions after the fact.
