Figure 4.

Kaplan‐Meier analysis of the cumulative hepatocellular carcinoma (HCC) recurrence in patients stratified based on the number of curative treatments for HCC before the direct‐acting antiviral agent (DAA) therapy (P < 0.0001). The probability of HCC recurrence for once curative treatment for HCC before the DAA therapy is indicated by the solid line (n = 262), that for twice curative treatments for HCC before the DAA therapy is indicated by the dotted line (n = 88), and that for thrice or more curative treatments for HCC before the DAA therapy is indicated by the solid and dotted line (n = 105). The number of curative treatments for HCC before the DAA therapy was unknown in four patients
