In the Cox regression model of univariate analysis, the experience of LR, an absence of ascites, a CTP score = 5, an AFP value lower than 400 ng/mL, and a tumor size > 3 cm or a number of tumor nodules ≥ 3 were all associated with better OS (p < 0.05) before PSM (Table 2). The gene discussed is AFP; the disease is neoplasm.
