Are you saying there have been studies showing approximately 0% reduced risk of infection from wearing a paper or cloth mask?

I'd have assumed that these masks are much less effective than an N95, but I haven't seen any data showing they have no effect.

There are no studies that I know of that show that cloth masks provide protection for the wearer. The consensus now seems to be that they are effective at decreasing the likelihood that a sick person spreads it to a healthy person if sick people wear them.
