COMMD3 and hepatocellular carcinoma: To further estimate the prognostic value of COMMD3 mRNA level for HCC patients, we performed multivariate analysis on COMMD3 mRNA level (high vs. low), age (≥60 vs. <60 years), sex (man vs. female), race (white vs. others), G stage (G3+G4 vs. G1+G2), TNM stage (III+ IV vs. I+ II), T stage (T3+T4 vs. T1+T2), and vascular invasion (Yes vs. No) (Table 4 and Table 5).
