> PS. This is bigger than “fractions of a percent”:

No, it isn't. If you'd bothered to read the content of the link I posted in the comment to which you're replying, you'd see that it's about the same paper.

That paper is mentioned numerous times in the thread you're commenting on, I've linked to it, as have others, and I've cited the absolute effect size: 0.09%.

The paper showed that there was an 11% drop on a baseline infection rate of 0.79%, in a fully unvaccinated population with very little natural immunity. It is the absolute best possible argument for masks, and it showed that cloth masks had no detectible effect, and that surgical masks had an effect size measured in tiny fractions of a percent.
