> These findings indicate that countries with high levels of mask compliance did not perform better than those with low mask usage. That could be because the majority of masks (e.g., the ultra-cheap blue ones) are - per the CDC - all but useless. That is, wear a mask (that's no mask at all) and you're all but unmasked. Oddly enough, currently, (e.g.) Philadelphia reinstated an indoor mask mandate, but made no requirement for an effective mask (according to the data / science). It makes no sense.
