Myocarditis complications more common after Covid infection than vaccination

&quot;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.&quot;<p>OK, did they get something mixed up in the article?<p>I really want to criticize them for having a 30 day window for the infection but a 7 day window for vaccine reaction, but I&#x27;m not sure the information is accurate.

Remember there is still survival bias here. We’re not seeing the complications from people who died of the infection.

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.<p>The &quot;clinical outcomes&quot; table isn&#x27;t stratified by age or sex so you can&#x27;t meaningfully conclude anything.
