Probability of survival with a Cerebral Performance Category (CPC) score of 1 or 2 until day 60 after the return of spontaneous circulation (ROSC), which was identical to survival to hospital discharge with a CPC score of 1 or 2; intention-to-treat (ITT) analysis. “No. Alive:” reflects total number of participants minus (1) those who died before the corresponding time point; and (2) those in whom neurologic failure (i.e. Glasgow Coma Scale score of ≤9) was confirmed (before the corresponding time point) and was followed either by death before hospital discharge (without any intervening neurologic failure free day) or by determination of a CPC score of 3 or 4 at hospital discharge (again, without any intervening neurologic failure free day). Therefore, “No. Alive” reflects patients who could still achieve hospital discharge with a CPC score of 1 or 2.
