Identification of Hypoxia-Related Differentially Expressed Genes and Construction of the Clinical Prognostic Predictor in Hepatocellular Carcinoma by Bioinformatic Analysis

Figure 6

The accuracy of hypoxia-related prognostic predictor (PP) in hepatocellular carcinoma patients. (a) The 1-, 3-, and 5-year risk score ROC (receiver-operating characteristic) curve analysis by integrating age, gender, tumor grade, and AJCC TNM stage. Kaplan-Meier (K-M) method was used to plot the survival curve for the training set (b) and the validation set (c). Risk score with clinicopathological features in univariate analyses (d) and in multivariate analyses (e). Red squares displayed risk factors, and green squares displayed protective factors.
