Prognostic and clinicopathological significance of glypican-3 overexpression in hepatocellular carcinoma: A meta-analysis

Figure 2 Meta analysis. Forest plot of the hazard ratio (HR) for the overall survival (OS) (A) and disease-free survival (DFS) (B) of hepatocellular carcinoma (HCC) patients. The combined HR and 95%CI demonstrated that an increased level of glypican-3 (GPC3) expression was associated with poorer OS and DFS in HCC patients (according to the fixed-effect estimations); ORs and 95%CIs in three studies evaluating the relationship between GPC3 expression and tumor vascular invasion (C) or hepatic cirrhosis (D) in HCC. OR > 1 implied that GPC3 overexpression was associated with tumor vascular invasion and hepatic cirrhosis; ORs and 95%CIs in three studies evaluating the relationship between GPC3 expression and tumor differentiation (E) or tumor TNM stage (F) in HCC; E: OR < 1 indicated that GPC3 overexpression was lower in patients with well-differentiated tumors than in those with moderately or poorly differentiated ones; F: OR < 1 indicated that GPC3 overexpression was lower in patients with stage I/II tumors than in those with stage III/IV tumors.
