AFP and cirrhosis of liver: While, the other characteristics such as gender (p = 1.000), age (p = 0.597), microsatilite (p = 0.781), liver cirrhosis (p = 0.414), number of tumors (p = 0.465), lymph node metastasis (p = 0.561), vein invasion (p = 0.275), TNM stage (p = 0.254), Edmondson-Steiner grade (p = 0.577), HBV infection (p = 0.414), HCV infection (p = 0.090), and serum AFP (p = 0.779) were not correlated with CLTA expression (Table S4).
