Kaplan–Meier disease-free survival analysis for HCC patients according to miR-22 level. The median value of miR-22 level was chosen as the cutoff point for separating miR-22 low-expression tumours (n=80) from miR-22 high-expression cases (n=80). P-value is shown with the use of log-rank test in SPSS 17.0.
