right, i was going to make a similar kind of critique (but probably less lucidly). the effect sizes are tiny and the confidence intervals overwhelm the supposed conclusions. seems to be motivated reasoning rather than impartial science.

covid may cause a rise in heart disease in unvaxed individuals relative to vaxed, but this study does nothing to support, and especially doesn't prove, that contention. one thing it does reveal is that the overall incidence rates for myo-/pericarditis are pretty small, vaxed or otherwise.

what would be more interesting is a comparative study of incidence relative to similar cardiopulmonary infections like the flu. that would tell us whether heart disease from covid is something to worry more about than our ambient worry over heart disease in general (which seems relatively mild compared to covid).
