The study was “self-controlled”. That is, individuals before being exposed to vaccine/covid were their own controls. This is a fairly robust technique if done right. You automatically avoid issues of your controls having different attributes to your test group. But obviously if your whole cohort is a year older after being exposed then the risk of myocarditis is higher purely based on the risk factor of age.

- scotty79 5y agoInteresting technique. I'm still not very convinced by this research. That myocarditis is so rare and the increase is so small. People might have changed their behavior in 28 days after getting the vaccine. Younger people especially. They might have started to expose themselves to other people more which might lead to them getting in contact with myriad of other mild viruses that might carry unknown risk of myocarditis.
