Hepatocellular Carcinoma in Liver Cirrhosis: Surgical Resection versus Transarterial Chemoembolization—A Meta-Analysis

Figure 4

Forest plot illustrating subgroup analysis of short- and long-term overall-survival comparing hepatic resection to TACE. The center of each square represents the hazard ratio for individual trial and each horizontal line represents its 95% CI. The size of the box is directly related to the “weighting” of the study. The center of the diamond represents the pooled hazard ratio and the width represents its 95% CI. For each subgroup (1, 3, and 5 years), the sum of the statistics is represented by the first three diamonds. The last diamond illustrates the overall result of the meta-analysis.
