YAP1 and gastric cancer: The multivariate Cox proportional hazards regression model 1 (did not include the combined variables (YAP1 and P62 expression, and Borrman and P62 expression)) showed that distant metastasis (hazard ratio (HR): 3.130, 95% confidence interval (CI): 1.483–6.607, P = 0.003) and TNM staging (HR: 2.964, 95% CI: 1.741–5.044, P = 0.000) were independently associated with the prognosis of GC (Table 2).
