Univariate analysis shows that in addition to albumin expression (P = 0.03), tumor, node and metastasis (TNM) staging (P = 0.007) and Barcelona clinic liver cancer (BCLC) staging (P = 0.002), the RGC classification was a significant indicator for OS (P = 9.4 × 10−6) in the Singapore cohort. The gene discussed is ALB; the disease is liver cancer.
