Notes: aECVs could not be evaluated because the venous vessels were not obviously enhanced in 1 patient; bas for the patients who underwent endoscopic variceal therapy, only EVs on endoscopy performed after CT during the same hospitalizations were evaluated; as for the patients who did not undergo endoscopic variceal therapy, EVs on endoscopy performed during the same hospitalizations were evaluated, regardless of the order of CT and endoscopy. CI, confidence interval; EVL, endoscopic variceal ligation; EIS, endoscopic injection sclerotherapy; CT, computed tomography; NSBBs, nonselective beta-blockers; MELD, model for end stage of liver disease; EVs, esophageal varices; ECVs, esophageal collateral veins; NA, not available.
