In the combined analysis of YAP expression and survival of patients with lung cancer, the OS of the patients with lung cancer with high YAP expression was significantly shorter than in patients with low YAP expression in the overall population (Ph = 0.327, I2 = 13.6%, crude HR = 1.652, 95% CI = 1.211–2.253) (Figure 3; Table 3), and even more so in the Asian population (Ph = 0.218, I2 = 30.6%, crude HR = 1.642, 95% CI = 1.195–2.257). This evidence concerns the gene YAP1 and lung carcinoma.
