The people making those recommendations are experts in the field and have all read the relevant research. Weighting the good studies vs. the bad ones, measuring evidence, etc. They literally exist to give guidance on world health matters based on the spectrum of results from all these different researchers.
And here you are, telling me that in your opinion, we should ignore their assessment and only trust these few specific papers that you choose to emphasize. (At least you've stopped advocating for ivermectin now?)
A bit of a paradox to get people to rely on your opinion when you've previously said we shouldn't rely on opinions isn't it? Or is it just that you don't like the WHO's opinion on World Health issues because they might be in the pocket of "big surgical mask".
