That's probably quite important if you are trying to control pandemic influenza, but SARS-COV-2 isn't influenza. Different pathogens have different characteristics, and thus different responses to protective measures. AFAIK, most influenzas are much more prone to airborne transmission than SARS-COV-2, where the main concern is droplet transmission (though some airborne transmission seems to occur), against which masks that are ineffective against airborne transmission can be quite effective.
You wouldn't judge the value of condoms in preventing the spread of AIDS by studies of how effective they were in preventing the spread of the flu, either.
