Figure 6

Time-dependent receiver operating characteristic (ROC) curves of the nomogram score and model based on TNM stage for CSS of RCC patients with lung metastases. (a) ROC at 1 year. The areas under the curve (AUCs) of the nomogram and TNM stage were 0.767 and 0.617, respectively. (b) ROC at 2 year. The areas under the curve (AUCs) of the nomogram and TNM stage were 0.780 and 0.618, respectively.
