Read your first link. Literally, from the abstract:
“The evidence base is limited in quantity and quality and insufficient to provide clear guidance“ [1].
The entire paper is about the “major evidence gaps.”

I have read many scientific, peer-reviewed papers on this subject. There is too much 'insufficient' data and too much correlation/causation issues. I am a hardware engineer, so am driven, delimited, and succeed or fail on the veracity of my data. I can generally depend on good data provided by suppliers and its efficacy because it is based on Physics. I have read may MS and PhD papers in botany and cellular biology, and a few CDC/NIH/FDA papers on the OT. I will conjecture that there are too many life scientists on these research teams and not enough physical scientists and engineers.
