In analyses using the KM web tool, the OS (HR = 1.33 [1.11–1.6], p = 0.0016), PPS (HR = 1.64 [1.3–2.06], p = 2.5e-05), and FP (HR = 1.43 [1.15–1.78], p = 0.0014) of GC patients with high EFNA3 expression (Figures 2C–E) values were significantly lower than those of patients with low EFNA3 expression. Here, EFNA3 is linked to gastric cancer.
