Identification of a five-long non-coding RNA signature to improve the prognosis prediction for patients with hepatocellular carcinoma

Figure 2 The 5-long non-coding RNA signature-based risk score predicted the overall survival of patients with hepatocellular carcinoma in the training set (n = 184). A: Kaplan-Meier analysis of patients’ overall survival in the high-risk (n = 92) and low-risk (n = 92) subgroups of the training set; B: The receiver operating characteristic (ROC) analysis of the risk score for prediction the overall survival of the training set. The area under the curve was calculated for ROC curves; C: The 5-lncRNA-based risk score distribution, patient survival status; D: Heatmap of the 5-lncRNA expression profiles in the high-risk and low-risk subgroups for the training set.
