*Cases where resuscitation was attempted.
†ROSC before hospital was not available for the OHCA sample in 2011–2012.
‡Cases with missing outcome data are excluded from the denominator.
§Cases where resuscitation was attempted, cardiac aetiology was presumed, bystander witnessed and initial rhythm of VF/VT.
OHCA, out-of-hospital cardiac arrest; ROSC, return of spontaneous circulation; SCA, sudden cardiac arrest.
