Can someone knowledgeable explain the current understanding of Covid’s long time effects? I thought it was still a big unknown and long COVID was still debated as to even having a clear definition.

If only there were some sort of link here with that sort of information!

94% accuracy sounds extremely bad, no?

So a fake test always saying "No" would be more accurate at 96.5% accuracy.

This is (probably) not a Long Covid story but I found that bloodletting (for which I even received money!) gave me back the energy that I was missing for the last few years (e.g. it was impossible to build stamina). I also read about a study about the positive effects of bloodletting[1] that somehow is not all the rage in mainstream news, which I find perplexing. If it might be so easy to improve your health (for some of us), why isn't this discussed or studied more broadly?

"the patients who gave blood had a significant reduction in systolic blood pressure (from 148 mmHg to 130 mmHg) as well as reduction in blood glucose levels and heart rate, and an improvement in cholesterol levels (LDL/HDL ratio)."

Sample size of 59 also seems worse than useless; I'm no researcher so maybe there's something I'm missing here but, doesn't seem very good.

Junk science?

The lower blood pressure I can explain by having a lower volume of blood. But the glucose and cholesterol have to go somewhere. Where do they go? Are they filtered in the process after blood letting?

If you read the actual link I don't think they're saying that using it as a covid test with some specific threshold of microclots has a 94% accuracy but just that the raw microclot count has a 94% accuracy.

The title on hn which implies that seems to be inaccurate and it's not the original title of the article.

The paper claims that 1/5 of people experience Long COVID after an infection. Given that approximately everyone has caught COVID by now, this does not track with how rarely I've heard of people with it.

Wikipedia lists much lower numbers on https://en.wikipedia.org/wiki/Long_COVID (6–7% in adults, ~1% in children, less after vaccination.) and seems to use a more liberal definition than this paper, as it mentions "Most people with symptoms at 4 weeks recover by 12 weeks" (while the paper only considers it "long COIVD" if symptoms last past 3 months).

I've found studies (peer reviewed, as far as I can tell) claiming anything from well under 10% to well over 30%.

What's going on here?
