Clinical outcome of small hepatocellular carcinoma after different treatments: A meta-analysis

Figure 1 Identification of studies for inclusion in the meta-analysis.

Figure 2 Comparison of methods for surgical resection and nonsurgical ablation for small hepatocellular carcinoma based on the overall survival rate and disease-free survival rate. A: 5-year overall survival rate; B: 3-year disease-free survival rate.

Figure 3 Comparison of adverse events and 1-, 2-, and 3-year overall survival rates between percutaneous ethanol injection and radiofrequency ablation for treatment of small hepatocellular carcinoma. A: Adverse events; B: 1-year overall survival rate; C: 2-year overall survival rate; D: 3-year overall survival rate. All analyses used the Mantel-Haenszel method.

Figure 4 Comparison between transcatheter arterial chemoembolization plus radiofrequency ablation and radiofrequency ablation alone as a treatment for small hepatocellular carcinoma based on overall survival rate. A: 1-year overall survival rate; B: 3-year overall survival rate; C: 5-year overall survival rate. All analyses used the Mantel-Haenszel method.
