Figure 3. Prognostic value of let-7e expression was evaluated by Kaplan–Meier survival analyses of HCC patients. (A) HCC patients who had high let-7e expression had significantly worse OS rates compared with those who had low let-7e expression (*P=0.046). (B) Compared with HCC patients who had low let-7e expression, those who had high let-7e expression had significantly worse DFS rates (P=0.030).
