Laparoscopic resection vs laparoscopic radiofrequency ablation for the treatment of small hepatocellular carcinomas: A single-center analysis

Figure 1 Overall and disease-free survival curves of the laparoscopically-treated hepatocellular carcinoma patients and their corresponding cumulative hazard curves. A: Overall survival curve of the laparoscopically-treated hepatocellular carcinoma (HCC) patients. Number of patients at risk at each time point is shown at top of the x-axis; B: Cumulative hazard for the corresponding overall survival curve; C: Disease-free survival curve of the laparoscopically-treated HCC patients. Number of patients at risk at each time point is shown at top of the X-axis; D: Cumulative hazard for the corresponding disease-free survival curve.
