ORs for the association between selected Utstein elements and good survival outcome defined as CPC 1–2 or GOS-E ≥5 (n=93)*
| Characteristics of OHCA | Adjusted OR (95% CI) |
| Ventricular fibrillation | 6.5 (1.5 to 27.8) |
| Witnessed Arrest | 2.5 (0.7 to 9.5) |
| Bystander CPR | 0.4 (0.1 to 1.8) |
| Male | 1.9 (0.5 to 8.1) |
| Home OHCA | 1.8 (0.5 to 6.8) |
| EMS response time | 1.0 (0.9 to 1.2) |
↵* ORs calculated using multivariable logistic regression using all variables listed.
CPC, Cerebral Performance Category; EMS, emergency medical services; GOS-E, Glasgow Outcome Scale-Extended; OHCA, out-of-hospital cardiac arrest; CPR, cardiopulmonary resuscitation.
