Table 4 Multivariate model of hyperoxemia versus normoxemia in relation to neurological outcome (CPC)

From: Associations between partial pressure of oxygen and neurological outcome in out-of-hospital cardiac arrest patients: an explorative analysis of a randomized trial

  OR 95% CI p value
Hyperoxemia (normoxemia reference) 1.24 0.81–1.89 0.314
TTM group (33 °C reference) 0.99 0.70–1.41 0.976
Age (per year) 1.07 1.05–1.09 < 0.001
Sex (male reference) 1.36 0.85–2.17 0.200
Chronic heart failure (yes/no) 2.14 1.01–4.54 0.048
Asthma/COPD (yes/no) 1.29 0.70–2.36 0.410
Bystander witnessed arrest (yes/no) 0.61 0.35–1.07 0.087
Bystander CPR (yes/no) 0.88 0.58–1.34 0.550
Time to ROSC (per min) 1.03 1.02–1.04 < 0.001
GCS-Motor (1 vs 2–5) 0.40 0.28–0.57 < 0.001
Circulatory shock on admission (yes/no) 1.58 0.89–2.80 0.118
First rhythm shockable (yes/no) 0.19 0.11–0.34 < 0.001
pH (per unit increase) 0.38 0.10–1.49 0.164
  1. CPC cerebral performance category, CPC 1–2 good outcome, CPC 3–5 poor outcome, CI confidence interval. OR odds ratio, TTM target temperature management, COPD chronic obstructive pulmonary disease, CPR cardiopulmonary resuscitation. GCS-M Glasgow Coma Scale-Motor, ROSC return of spontaneous circulation. OR < 1 indicates better outcome
