INHBB and gastric cancer: Subgroup analysis indicated that high expression of INHBB was significantly correlated with poor OS in GC in the following categories: patients less than 65 years old (HR = 2.73, p = 0.001), male patients (HR = 1.60, p = 0.023), T4 (HR = 2.25, p = 0.015), N2 (HR = 2.5, p = 0.029), M0 (HR = 1.67, p = 0.006), G3 (HR = 2.00, p = 0.002), pathological stage III (HR = 2.23, p = 0.002), residual tumor R0 (HR = 1.96, p = 0.001), and those with gastroesophageal junction (HR = 4.88, p = 0.041).
