Table 4.
Multivariable logistic regression analysis for the primary outcome in the whole population of pooled ARREST and PRAGUE-OHCA randomised trials (OR > 1: unfavourable outcome, OR < 1: favourable outcome).
| Variable | Odds ratio | 95% CI | p-value |
|---|---|---|---|
| Sex male | 1.61 | 0.57–4.59 | 0.37 |
| Age >55 | 1.83 | 0.89–3.77 | 0.1 |
| Initial rhythm “Shockable” | 0.05 | 0.02–0.16 | <0.0001 |
| Public place Yes | 0.8 | 0.4–1.62 | 0.54 |
| Time of CPR <30 | 0.07 | 0.02–0.21 | <0.0001 |
| Time of CPR ≥30 & <45 | 0.27 | 0.11–0.66 | 0.004 |
| Epinephrine >4 mg | 1.82 | 0.81–4.07 | 0.15 |
| Invasive approach | 0.25 | 0.11–0.54 | 0.0004 |
| Study–ARREST | 1.92 | 0.45–8.16 | 0.38 |
Bold: p value is less than the level of significance (<0.05).
