Association between Tumor Vasculogenic Mimicry and the Poor Prognosis of Gastric Cancer in China: An Updated Systematic Review and Meta-Analysis

Figure 2

Forest plot of hazard ratios (HRs) in the random-effect model. The HR of overall survival of vasculogenic mimicry- (VM-) positive cancer patients was compared with VM-negative cancer patients. Each individual study is represented by the red square, and the pooled datasets are indicated by the diamond, representing the 95% confidence interval (CI) of each study. An HR > 1 implied a worse survival for the cancer patients. The size of each study represents the weighting factor (1/standard error [SE]) assigned to it.
