Indeed, I had posted it here seeking more informed opinions by people who have followed long covid research during the past year.
When it appeared on biorXiv yesterday a couple of researchers picked it up with worried statements. What I could assess myself were the position of the authors, and format details which look as if they expect high impact (I’m in a whole different field, so take that with a grain of salt).
Maybe scientists will have reason to check in humans next after this result..
