This prognostic model consists of nine genes, including UBLCP1, CCDC42, AQP5, KCTD8, LARS, SMS, TNNT3, RUVBL1, and YIF1B. We clearly illustrated the impacts of these nine gene expression levels on the overall survival risk of HCC patients by a combination of the risk score distribution, survival status scatter plot, and gene expression heatmap (see Figure 4C). This evidence concerns the gene AQP5 and hepatocellular carcinoma.
