The results showed that the expression levels of SERPINE1 (Figure 8G), SPP1 (Figure 8H), CCNB1 (Figure 8I), and NQO1 (Figure 8K) had prognostic predictive value in HCC patients, while CYP2C9 (Figure 8J) and LCAT (Figure 8L) had no significant prognostic value. Here, NQO1 is linked to hepatocellular carcinoma.
