  • CARES indicates Cardiac Arrest Registry to Enhance Survival; EMS, emergency medical services; and ROC, Resuscitation Outcomes Consortium.

  • * ROC Epistry incidence counts all cardiac arrests (with cardiac and noncardiac pathogenesis), whereas CARES incidence includes cardiac arrest of presumed cardiac origin only.

  • “Untreated” refers to cases that did not receive resuscitation treatment because patients were either dead on EMS arrival or had existing do-not-resuscitate orders.
