After PSM, treatment allocation (HR = 0.406, 95% CI = 0.242–0.680), Child–Pugh class (HR = 1.740, 95% CI = 1.061–2.854), HGB level (HR = 0.984, 95% CI = 0.968–0.999), ALB level (HR = 0.937, 95% CI = 0.887–0.990), tumor number (HR = 1.776, 95% CI = 1.057–2.983) and major vascular invasion (HR = 1.992, 95% CI = 0.894–4.438) were potential risk factors of OS (Table 3). The gene discussed is CYGB; the disease is neoplasm.
