Identifying survival protective factors for chronic dialysis patients with surgically confirmed acute mesenteric ischemia

Figure 1 Kaplan–Meier plot for in-hospital survival with a surgery delay less than or not less than 4. 5 d. In patients with a surgery delay < 4.5 d, the 20-d discharge probability was 44.4%, whereas the discharge probability was 50% on day 22. For surgery delays ≥ 4.5 d, the 20-d discharge probability was 14.9%, whereas the discharge probability was 50% on day 54. Surgery delay was defined as the time from the onset of signs and symptoms of acute mesenteric ischemia to surgery.
