Table 2
Extended Cox-regression model for the effect of epinephrine on prehospital ROSC rate.
| Predictor | Phase 1 (0–10 minutes) | Phase 2 (11–20 minutes) | Phase 3 (>20 minutes) | HR (95% CI) | | HR (95% CI) | | HR (95% CI) | |
| SALS | 0.56 (0.43–0.72) | <0.001 | 2.15 (1.36–3.39) | 0.001 | 1.04 (0.36–3.01) | 0.936 | Shockable | 19.42 (14.43–26.12) | <0.001 | 21.71 (13.05–36.12) | <0.001 | 6.18 (2.14–17.83) | 0.001 | Epinephrine: SALS | 2.02 (1.08–3.78) | 0.028 | 6.94 (4.15–11.61) | <0.001 | 7.43 (2.92–18.91) | <0.001 | Epinephrine: SALS : shockable | 0.20 (0.08–0.47) | <0.001 | 0.07 (0.04–0.13) | <0.001 | 0.3 (0.1–0.91) | 0.033 |
