   New paper on Masks:

   Some claim scientific studies show masks don’t work, or that surgical masks are as good as N95s. Just released paper shows this claim is false. Masks work, and N95 respirators give a much higher benefit than surgical masks.

   The controversy about N95 respirator and mask efficacy is based on claims that studies (RCTs and meta-analyses) have no observed effect. Our paper shows these claims result from the use of incorrect mathematical equations.
