Calibration curves and decision curve analysis of the nomogram. (A) Calibration curves of the nomogram: The X-axis represented the predicted probability estimated by nomogram, whereas the Y-axis represented the actual observed rates. the red line represented the apparent prediction of nomogram, the green line represented the fitting line after bias-corrected. the dashed line represented the ideal estimation. Calibration curves showed the actual probability is relatively close to the prediction of nomogram. (B) Decision curve analysis for the models 1-5: The X-axis represented the threshold probability that was where the expected benefit of treatment was equal to the expected benefit of avoiding treatment. The Y-axis represented the net benefit. The purple line represents the hypothesis that all patients are ADC, and the red line represents the hypothesis that all patients are SCC. Other curves are shown in the figure, representing models 1-5 in turn.
