I'm not sure this is any different than what we've believed earlier.  In the face of "uncommon general mask use", wearing a mask will reduce infection rates by less than 50%.  I don't have the time to look through notes, but my impression was that wearing a mask gave you maybe a 20-40% decreased risk and there was some possibility that it could make your illness less severe (i.e., the UCSF Variolation commentary).  Too bad the study above didn't assess the degree of illness of those infected.
