Continuous data were evaluated using two-sample t tests and categorical variables were analyzed using Chi-square tests. Data represent the number of patients with percentage in parentheses or the mean ± SD. RF: Radiofrequency; HBV: Hepatitis B virus; HCV: Hepatitis C virus; NBNC: Non-B non-C; INR: International normalized ratio.
