Log transformation was used on the AFP and PIVKA-II values to account for the large range of values for both markers. Log values of serum levels of AFP (a) and PIVKA-II (b) in HBV-related HCC and control group were compared by box plots. AFP: alpha fetoprotein, PIVKA-II: prothrombin induced by vitamin K absence- II. *P < 0.01
