Regarding the relationship between an independent OAG score and clinical features, the high OAG score group had more HCC patients with higher alpha-fetoprotein (AFP) levels (p < 0.01), T stages (p < 0.01), clinical stages (p < 0.05), grades (p < 0.05), and macro- or micro-vascular invasions but a lower proportion of HBV-infected HCC patients (p < 0.001, Figure S7). The gene discussed is AFP; the disease is hepatocellular carcinoma.
