PSMD1 and hepatocellular carcinoma: In contrast, HCC-based variables such as gender (p = 0.369), age (p = 0.254), Child–Pugh classification (p = 0.515), tumor number (p = 0.5), microvascular invasion (p = 0.549), and Edmondson grade (p = 0.438) were not associated with PSMD1 overexpression (Table 2).
