Figure 2.

Cumulative recurrence rate in early-stage hepatocellular carcinoma patients treated with resection or radiofrequency ablation (dotted lines, 95% confidence intervals). (A) Whole study population. (B) Comparison of the next 5-year cumulative recurrence rate (5–10 years) among patients with 5 recurrence-free years (the dashed line) and the first 5-year cumulative recurrence rate in the total patients (the solid line). The index date was the time of diagnosis for a total of 1,451 patients (indicated by the solid line), and 5 years after diagnosis the 487 survivors at 5-year follow-up without recurrence (indicated by the dashed line).
