This preprint is actually a companion paper to their already published paper in Nature where they do not stratify by age and sex together. In principle this is bad because we know already very well that it affects more young men. I think they made the situation even worse by stratifying only for myocarditis and not for pericarditis and cardiac arrhythmias that according to their paper are much more likely with COVID-19 because it did not register at all for vaccines. This means that people are now getting a very wrong/incomplete picture of the risk benefit relationship. Naturally cardiac issues are not the only possible problems because COVID-19 is systemic disease that can affect many organs and can cause a lot of trouble even without hospitalization.
