Sure. Here’s a meta of 14 studies. But, there are hundreds saying the same thing…
“In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks (RR 0.78, 95% CI 0.51–1.20; I2 = 30%, p = 0.25)”

Also note, what you posted is not a scientific study. It’s a made up model. Real world evidence is falling in line with previous scientific knowledge. Countries w/out mask mandates have no statistical difference in transmission, as expected. But, the whole thing has been politicized.
- andi999 5y agoEven that study believes that good masks help:"We did not consider the use of respirators in the community. Respirators are tight-fitting masks that can protect the wearer from fine particles (37) and should provide better protection against influenza virus exposures when properly worn because of higher filtration efficiency."
- chrischattin 5y agoThere are multiple studies cited.
- andi999 5y agoBurden of proof is usually on the person making a claim.
- chrischattin 5y agoRight. In this case, it’s on those arguing for mask mandates.
- jquery 5y agoThe same metastudy says hand washing isn’t statistically significant in stopping pandemic flu spread, but is careful to note that doesn’t mean it’s ok not to wash your hands. There are many other diseases which are prevented by washing your hands. Generalizing from influenza to COVID-19 seems like a big assumption.
