Correspondingly, the OAG score was positively correlated with AFP level (p < 0.001), T stage (p < 0.001), clinical stage (p < 0.001), high grade (p < 0.05), and vascular invasion, and HBV-infected HCC patients had the lowest OAG score (p < 0.001, Figure S8). This evidence concerns the gene AFP and hepatocellular carcinoma.
