Here's what low certainty grade results mean: "low certainty (our confidence in the effect estimate is limited; the true effect could be substantially different from the estimate of the effect);". Just so we're clear: you've never linked to research to support any of your points, because you're not able to, are you?

You're acting like its definition is "it's probably the opposite, and thus is evidence for my argument".

  And last time you posted those links I pointed out that they were for the same paper and the paper doesn't support your point. Here's someone explaining what GRADE means: https://twitter.com/dnunan79/status/1269014574478626819 https://twitter.com/dnunan79/status/1269014574478626819 "I teach GRADE If something has “low quality” evidence, it means the observed estimate is highly likely to be different from the truth. Face masks = low quality evidence. So what’s the point of GRADE if we can conclude “evidence shows”?" EDIT: Your link even says this > Further high-quality research, including randomised trials of the optimum physical distance and the effectiveness of different types of masks in the general population and for health-care workers' protection, is urgently needed

    OK, so let's apply these standards to you. You state here: https://news.ycombinator.com/item?id=23728926 https://news.ycombinator.com/item?id=23728926 > If you have the correct behaviour (hand washing, distancing) the mask provides you no benefit. Do you have a RCT with a high or at least moderate confidence/certainty finding backing that assertion up?

      No, I'm tired of playing your stupid games. You've failed to post a link that supports any of your claims. The only link you posted directly contradicts your claim. Clearly, there's no point in me posting any links if you're going to misrepresent what they say. Cochrane have a bunch of research on masks and handwashing.
