Figure 3. Construction of a novel nomogram based on the TCGA-KIRC cohort. (A, B) Combining age and tumour stage, univariate and multivariate Cox regression analyses were performed to determine the risk score as an independent risk factor for ccRCC patients. (C) A nomogram combining age, tumour stage, and risk score was constructed; (D–F) Calibration charts at 1, 3, and 5 years were plotted to assess the accuracy of the nomogram; (G) ROC curves were used to further validate the ability of the nomogram to assess the patients’ prognosis at 1, 3, and 5 years.
