Non-invasive model for predicting high-risk esophageal varices based on liver and spleen stiffness

Figure 3 Adjusted decision curve analysis of data of patients. A: Modelling group; B: External validation group. The black line indicates that in extreme cases, the new model predicted that there were no high-risk esophageal varices in all patients with viral cirrhosis, and the clinical net benefit was 0. The gray curve indicates that in extreme cases, the new model predicts there are high-risk esophageal varices in all patients with viral cirrhosis, the clinical net benefit is the negative slope. The red line indicates that the new model has a clinical net benefit. The red line is higher than the black and gray lines, indicating that patients in the modelling group can benefit from the new model.
