Laboratory studies presented as median (IQR) and analyzed using the Wilcoxon rank-sum test.

*Deceased includes patients who died due to myocarditis-related complications within a 90-day window.

†Defined as: second-degree AV block Mobitz type I or II, high-grade AV block and third-degree AV block.

AV, atrioventricular; CK, creatine kinase.
