(a) The comparison of ROC curves between the prediction model with the predictor namely imprinted gene detection and without it. (b) The decision curve analysis (DCA) curves showing the net clinical benefit of the models. Model 1 represents the model without the predictor namely imprinted gene detection and Model 2 with it. The curve All and None represent the situation that all cases are intervened and none of them are intervened, respectively
