Fig. 2From: Tumor apelin, not serum apelin, is associated with the clinical features and prognosis of gastric cancerThe relation of tumor Apelin expression status with the survival of GC patients by Kaplan-Miere curves. a Patients with strong Apelin staining had significantly shorter overall survival period 22.6 ± 4.9 months) compared to those with low Apelin expression (29.1 ± 3.7, months) and those with weak or negative Apelin staining (30.4 ± 6.4 months). b GC patients with high and low serum Apelin had similar overall survival period (26.9 ± 5.2 vs. 26.4 ± 2.9, months, P = 0.187 by log-rank test, Fig. 2b)Back to article page
