Are you serious? Even if you don't know/believe an actual paper, you can always look at first principles: 1) If N95 masks didn't work, all doctors and nurses in ICUs treating covid patients would get sick quite quickly. But that didn't, and in fact they got sick at a similar rate to other doctors (this is from Peru where they had lots and lots of covid) 2) These masks literally stop the virus from passing into your respiratory system. So why would you be surprised if they prevent disease transmission?

"all doctors and nurses in ICUs treating covid patients would get sick quite quickly." But that's doctors and nurses in a highly controlled environment where we know there is an awful lot of virus particles around. That controlled environment doesn't occur elsewhere, so you are comparing apples and pears. Leakage round the side, not wearing the masks fully, not changing often enough, etc. all apply in the field not the hospital, and even then the network effects can outstrip the filtering effect. Concentrations matter - as it does with radiation where high radiation areas damage the body and then when it drops below a certain level there is little impact at all. Extrapolating from hospital to elsewhere is problematic and simply not supported by the evidence. " These masks literally stop the virus from passing into your respiratory system." Again in controlled environments, not in the field where that level of protection isn't available nor is it managed, changed or worn properly in all cases. The reality on the ground shows that. There is no detectable effect outside really controlled environments without a high degree of curve fitting and bias. Texas has not exploded has it. The downvotes say it all. People no longer wants to discuss rationally the possibility that they may be mistaken. It has become a religious crusade to do with identity. The motto of the Royal Society is "Nullus in Verba" - take nobody's word for it. The essence of science is to question, not censor. We appear to have forgotten that.
