Values indicate n (%) unless otherwise stated. Comparisons are shown between SCA triggered by sports-related activity and non-sports-related activities. CPR indicates cardiopulmonary resuscitation; and SCA, sudden cardiac arrest.
*
Percentages are based on the total number of cases with nonmissing data.
†
Information regarding whether resuscitation was attempted (yes/no) was available for 154 cases; those missing resuscitation attempted status (n=32) had inadequate data to determine whether resuscitation was or was not attempted.
