Figure 3. Construction of the 8-IRlncRNA classifier for predicting prognosis of BLCA. (A) Patients with BLCA were sorted by increasing risk score in the training set. (B) Living status of BLCA patients in the training set. (C) Heatmap of eight IRlncRNAs expression profiles of different risk groups in the training set. (D, E) Kaplan-Meier analysis for overall survival (OS) of BLCA patients based on the risk stratification in the training set (D) and validating set (E). (F, G) Receiver operating characteristic (ROC) analysis for OS prediction including 1-, 3-, 5-year of BLCA patients in the training set (F) and validating set (G).
