CPR Before Defibrillation.
| Outcome | Certainty | Studies | No. of Patients | Results |
|---|---|---|---|---|
| 1 yr with favorable neurological outcome | Low (risk of bias, imprecision) | Wik 2003117 | 200 | No difference: Relative risk 1.15 (95% CI, −0.57 to 2.34), 19 more patients/1000 (−54 to 167) |
| Hospital discharge with favorable neurological outcome | Low (inconsistency, imprecision) | Wik 2003, Baker 2008, Stiell 2011, Ma 2012117, 118, 234, 235 | 10 424 | No difference: Relative risk 1.02 (95% CI, −0.01 to 0.01), 1 more patient/1000 (−7 to 11) |
| Survival to 1 yr | Low (risk of bias, imprecision) | Wik 2003, Jacobs 2005117, 233 | 456 | No difference: Relative risk 1.19 (95% CI, 0.69–2.04), 18 more patients/1000 (−29 to 98) |

CPR, cardiopulmonary resuscitation; and ROSC, return of spontaneous circulation.
Both relative and absolute risks are written as mean values (95% CIs).
