Fig. 2. Validation of the prognostic lncRNA signature for hepatocellular carcinoma.
(A) The upper graph shows the relationship between survival time and risk score, the medium graph shows the distribution of lncRNA risk score, the bottom heat map shows expression patterns of six-lncRNA signature for LIHC patients. (B) The Kaplan-Meier curve of different tumor groups based on the median risk score. (C) The ROC curve for the risk score, age, gender, grade, and TNM stage.
