  1. Data presented as number (percentage). P values calculated using chi-square test
  2. aPatients who had initially nonshockable rhythms and received no shock(s) during EMS resuscitation
  3. bPatients who had initially nonshockable arrest rhythms and subsequently received shock(s) owing to conversion to shockable rhythms during EMS resuscitation
  4. cSurvival with favorable neurological outcome defined as Cerebral Performance Category of 1 or 2 at 1 month after cardiac arrest
  5. CI confidence interval, EMS emergency medical service, ROSC return of spontaneous circulation
