The results showed that the low expression group of HCC patients with CDKN2A (Figure 4B, p = 0.002), DLAT (Figure 4C, p = 0.002), DLST (Figure 4D, p = 0.014) and GLS (Figure 4E, p = 0.022) and PDHA1 (Figure 4F, p = 0.023) had better survival than the high expression group. This evidence concerns the gene PDHA1 and hepatocellular carcinoma.
