Figure 5. Heatmap and nomogram construction and validation of the distribution of model signatures and clinicopathological variables. (A) Heatmap showing the distribution of clinicopathological factors and eight lncRNAs associated with prognostication. (B) For ccRCC patients, survival at 1, 3 and 5 years was predicted by nomogram survival in conjunction with risk scores and clinicopathological factors. (C–E) Calibration curves and Hosmer-Lemeshow test for the validation of the predicted probability of 1, 3, 5-year survival. Abbreviations: lncRNAs: long-chain non-coding RNAs; T: tumor size; M: metastasis; OS: overall survival; ccRCC: renal clear cell carcinoma.
