AFP and neoplasm: The LLR group tended to have more female patients (P < 0.001), smaller tumor size (P < 0.001), lower alpha-fetoprotein (P = 0.022), more recent cases (P < 0.001), more minor resections (P < 0.001), lower WBC count (P = 0.006), lower platelets (P = 0.010), lower aspartate aminotransferase and alanine aminotransferase (P < 0.001 for both), lower total bilirubin (P = 0.005), higher sodium (P = 0.002), and lower incidence of transfusion (P < 0.001) than the OLR group.
