On: The science of mask-wearing hasn’t changed, so why have our expectations?

[DanBC]

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:

"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
