INHBB and gastric cancer: Then, we further analyzed the data using multivariate Cox analysis and found that INHBB expression had a significant relevance with OS (HR = 2.014, 95% CI = 1.365–2.974, p < 0.001), as well as age (HR = 1.519, 95% CI = 1.020–2.261, p = 0.039) and residual tumors (HR = 2.844, 95% CI = 1.637–4.940, p < 0.001) (Figure 4A); these results suggested that these three indicators may be independent risk factors in GC.
