From: Machine learning-based nomogram for 30-day mortality prediction for patients with unresectable malignant biliary obstruction after ERCP with metal stent: a retrospective observational cohort study

Fig. 5

The calibration curve for nomogram. The nomogram-predicted short-term mortality probability is plotted on the x-axis, and the observed short-term mortality on the y-axis. A perfect prediction would correspond to a 45° grey dashed line. The blue solid line represents the cohort (training or test), and the red solid line represents the bias corrected by bootstrapping (B = 1000 repetitions), indicating the observed nomogram performance. Calibration curves for predicting short-term mortality in the training (A) and test (B) cohorts. MBO, malignant biliary obstruction
