Can anyone comment on these two papers?
https://pubmed.ncbi.nlm.nih.gov/37738335/
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9294036/
They're both published by NIH. I never heard anything about this.
Is this known by most everyone, and I just haven't been paying enough attention?
How significant is this? Is it within the bounds of "normal", or is it well outside it?
