Model effects of RSF and AJCC criteria-based tumor staging in predicting 5-year OS and 10-year OS after surgical resection in patients with cT1b stage RCC. The subject work characteristics (ROC) curves for the training and test sets illustrate the discriminative power of the two predictive models and show the area under the curve (AUC) values for the ROC curves of the two models (A–D). Calibration curves for the training and test sets illustrate the accuracy of the predictive ability of the two models (E–H).
