Yet another study with a deliberately misleading headline that ignores stratification. Look at Table 2 and the actual results are clear as day, 18-24 has 44% post-vax and 19% post-covid and males have 84% post-vax and 67% post-covid. Two-variable stratification would probably give even more severe discrepancies.

The "clinical outcomes" table isn't stratified by age or sex so you can't meaningfully conclude anything.

"Participants had postvaccination myocarditis (within 1 week of COVID-19 mRNA vaccination; 588 patients [12%]), post-COVID myocarditis (within 30 days of infection; 298 [6%]), or conventional myocarditis (3,779 [82%]). The team also compared medical management in the three groups after hospital release." OK, did they get something mixed up in the article? I really want to criticize them for having a 30 day window for…

Ooh nice catch, that didn't jump out to me at first skimming. In addition to this issue you noted, the other more fundamental issue is that their "clinical outcomes" table is not stratified in any fashion.

So the results are meaningless, we know from previous studies that young makes are more likely to get vax myocarditis than covid myocarditis, so all this study effectively tells us is that younger people are better at healing than older people.
