YAP1 and gastric cancer: The multivariate Cox proportional hazards regression model 2 (did not include the individual variables (YAP1 protein expression and P62 protein expression)) showed that distant metastasis (HR: 2.817, 95% CI: 1.328–5.978, P = 0.007), TNM staging (HR: 2.923, 95% CI: 1.711–4.995, P < 0.001), YAP1 and P62 expression (HR: 1.334, 95%CI: 1.045–1.704, P = 0.021) were independent predictors of the prognosis of GC (Table 2).
