Really interesting paper. Thanks for sharing! Here's a link directly to the published paper:

I found this part interesting in the STAT article because it seems to explain so many of the diverse symptoms that don't seem linked at first:

“Low serotonin levels weaken vagus nerve signaling, the gut-brain connection that could explain neurocognitive problems that are one hallmark of long Covid. Serotonin signaling can also affect blood clotting, the GI tract, and the central nervous system, making it one of the most important neurotransmitters in the body, not just in the brain where it can be involved in anxiety and depression. The more long Covid symptoms patients had, the lower their peripheral serotonin levels, the study found.”
