Calibration curves for model prediction of WD cirrhosis. Note: The model’s predicted probabilities were plotted on the x-axis, while the actual positive occurrence rate was plotted on the y-axis. The solid line (diagonal line) represented the ideal model, and the dashed line represented the calibration of the model established in this study. After conducting 500 iterations of bootstrap internal sampling, the model’s calibration analysis showed a Brier score of 0.102 and a p-value of 0.839(>0.05). These results indicate a high level of consistency between the predicted and actual outcomes
