The analysis was stratified by sex, age, H. pylori infection, TNM stage, and tumor size, and the results demonstrated that EPHA5 Pm was marginally associated with the GC prognosis in the younger subgroup and in the tumor larger than 5 cm subgroup, with borderline statistical significance (HRb = 0.645, 95% CI [0.409–1.016], P = 0.059 and HRb = 0.689, 95% CI [0.462–1.025], P = 0.066, Tables S7 and S8). The gene discussed is EPHA5; the disease is gastric cancer.
