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

Figure 3 Validation of the prognostic value of the 5-long non-coding RNA signature for the hepatocellular carcinoma patients in the test group. A: Kaplan-Meier analysis indicated that patients in the high-risk (n = 97) subgroup exhibited significantly poorer survival than the low-risk subgroup (n = 89) in the test group; B: The receiver operating characteristic analysis of the risk score for predicting the overall survival of the test set; C: The 5-long non-coding RNA (lncRNA)-based risk score distribution, patient survival status; D: Heatmap of the 5-lncRNA expression profiles in the high-risk and low-risk subgroups of the test set.
