  • QRS duration was determined at the time of myocarditis diagnosis. For the QRS duration row, the OR reflects the MACE risk for an increase of 10 ms from the mean value across the myocarditis cohort. For the age row, the OR reflects the MACE risk for an increase of 1 year. For all other rows, the ORs reflect the MACE risk comparing those with the designated condition compared with those without.

  • OR, odds ratio.
