Predictive performance of the radiomic, clinical and combined models in the training and test cohorts. (a, b) show the ROC curves of the different models in the training and test cohorts. Decision curve analysis (c, d) illustrates the net clinical benefits of the prediction model. The y-axis represents the net benefit and x-axis represents the threshold probability. The blue line indicates “treat all” and the pink horizontal line denotes “treat none.” ROC, receiver operating characteristic curve
