Fig. 3. Comparative RFS in response to combination of RFA and TACE vs Fig. 3. Comparative RFS in response to combination of RFA and TACE vs. RFA alone for HCC.Meta-analysis demonstrated that RFA plus TACE therapy was associated with significantly higher RFS than that RFA monotherapy. CI = confidence interval, HCC = hepatocellular carcinoma, RFA = radiofrequency ablation, RFS = recurrence-free survival, SE = standard error, TACE = transcatheter arterial chemoembolizaton Fig. 3.
