  1. A total of 1,494 of the 1,667 patients had complete data and were included in the analysis. A cerebral performance category of 1 or 2 at hospital discharge is considered a good neurological outcome. * P <0.05. CI, confidence interval; COPD, chronic obstructive pulmonary disease CPR, cardiopulmonary resuscitation; ROSC, return of spontaneous circulation; OR, odds ratio.
