YAP1 and gastric cancer: We revealed that a higher YAP1 expression level was significantly related to a poorer prognosis in pancreatic cancer (OS, HR = 2.14, 95% CI = 1.41–3.26, p = 0.00026; relapse free survival (RFS), HR = 5.06, 95% CI = 2.06–12.42, p = 9.1e−0.5) and gastric cancer (OS, HR = 1.31, 95% CI = 1.05–1.64, p = 0.015; first progression (FP), HR = 1.53, 95% CI = 1.15–2.03, p = 0.003) (Figures 4G,H,K,L).
