As shown in Figure 2, due to high heterogeneity (I2 = 80%), we found that high VEGF expression was associated with shorter OS in patients with endometrial carcinoma using a random-effects model (HR = 2.44, 95% CI = 1.15–5.16, I 2 = 80%, P = .02). This evidence concerns the gene VEGFA and endometrial carcinoma.
