Cumulative proportion of patients who died before hospital discharge. The cumulative proportion of patients who died before hospital discharge is displayed for the 35 patients for whom the health system capacity to provide extracorporeal membrane oxygenation (ECMO) at a specialized center was available (blue) and the 55 patients for whom the health system capacity to provide ECMO was unavailable (red). Groups were compared using Cox proportional hazards regression, adjusting for age, acute kidney injury, and receipt of vasopressors. CI = confidence interval.
