> 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);".
You're acting like its definition is "it's probably the opposite, and thus is evidence for my argument".
Here's someone explaining what GRADE means:

"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
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?
