Figure 2

Kaplan–Meier survival curve used to evaluate the effect of end-stage kidney disease (ESKD) on the rate of attaining sustained return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiac arrest (OHCA) for the evaluated time point, emergency department (ED) stay (survival until hospital admission). Patients with ESKD (blue). Patients without ESKD or CKD (red). The x-axis shows the time in hours of ED stay, and the y-axis shows the sustained survival probability of OHCA patients with cardio-pulmonary resuscitation (CPR).
