Second, we divided patients into another four groups in order to analyze the prognostic value of combined ELF and c-Myc levels for patients with HCC: ELF high expression/c-Myc high expression (EhMh), ELF low expression/c-Myc high expression (ElMh), ELF high expression/c-Myc low expression (EhMl), ELF low expression/c-Myc low expression (ElMl). The gene discussed is MYC; the disease is hepatocellular carcinoma.
