Yes, if you see the same thing for many years you gain more certainty over the signal, regardless of the strength of the signal. But a small signal is still small, regardless. And it's always incorrect to average together a high-risk group and a low-risk group and claim that everyone is at medium risk. > More likely, what's happening is that people who haven't fully recovered from covid are getting blood clots, and that's damaging their organs and sometimes killing them, but after a few months they do fully recover and so these problems stop — unless they get covid again. That's one hypothesis. Here's another: people (especially older people) deferred medical care throughout 2020 and 2021. They are seeking that medical care now. Undiagnosed heart problems are now being diagnosed. And oh yeah...they got a Covid test somewhere along the way. Often for (wait for it...) hospital admission. I'm not in love with this hypothesis; it's just the first one I thought of. There are actually a ton of plausible reasons why you'd see slightly elevated rates of whatever in a group of older, less-healthy people. Claiming that the virus caused it through a mystery mechanism is a wild leap to conclusions.
