Nucleotide variants in hepatitis B virus preS region predict the recurrence of hepatocellular carcinoma
Figure 1. Two HBV preS variants in the tumor tissues and sera predicted an unfavorable recurrence-free survival. (A) the tumor tissues. (B) the sera. Patients were split into two groups according to the presence (or absence) of the variant. Kaplan–Meier curves were plotted to visualize the difference.
