For the subgroup analysis, several factors were entered into the Cox regression analysis to screen the factors that may affect the recurrence and survival, including times of adjuvant TACE, liver cirrhosis, AFP level (<400 or ≥400), tumor size (≤5 or >5), tumor number (1/2), Edmondson grade (I–-IV), and MiVI. The gene discussed is AFP; the disease is cirrhosis of liver.
