Prognostic model for esophagogastric variceal rebleeding after endoscopic treatment in liver cirrhosis: A Chinese multicenter study

Figure 2 The nomogram, time-dependent concordance index and calibration curve. A: The nomogram for predicting variceal rebleeding; B-E: Risk stratification was based on the total points: Low-risk group (score < 117.3, green background), medium-risk (score 1173-142.7, yellow background) and high-risk (score > 142.7, red background). The time-dependent concordance index (C-index) of the rebleeding event prediction following endoscopic treatment model compared with other existing scores/criteria for the predicting variceal rebleeding in the derivation cohort (B) and in the external validation cohort (D). Calibration curves for 6 weeks, 1 year, and 2 years variceal rebleeding prediction in the derivation cohort (C) and in the external validation cohort (E). WBC: White blood cell; AST: Aspartate aminotransferase; ALB: Albumin; REPET: Rebleeding event prediction following endoscopic treatment.
