INHBB and gastric cancer: Simultaneously, we conducted a Kaplan–Meier survival analysis of DSS and PFI to identify the prognostic role of INHBB in GC; the results showed that INHBB expression correlated with adverse prognosis of PFI (HR = 1.66, p = 0.006) and DSS (HR = 2.08, p = 0.001), subgroup analysis of DSS and PFI showed that T3/T4, N2, M0, R0, G3, age less than 65 years old, no barretts esophagus, no reflux history, and anatomic neoplasm subdivision cardia/proximal are associated poor DSS and PFI in GC (Supplementary Figures S4, S5).
