Expression and clinical significance of CD73 and hypoxia-inducible factor-1α in gastric carcinoma

Figure 3 Receiver operating characteristic curves of clinicopathological variables, CD73 expression and hypoxia-inducible factor-1α expression based on outcomes of gastric carcinoma patients. CD73 expression (AUC = 0.850; P < 0.001), hypoxia-inducible factor-1α (HIF-1α) (AUC = 0.582; P = 0.247), AJCC stage (AUC = 0.765; P < 0.001), CD73/HIF-1α (AUC = 0.275; P = 0.001), Borrmann type (AUC = 0.472; P = 0.689), metastasis (AUC = 0.584; P = 0.235), nodal status (AUC = 0.572; P = 0.310), differentiation (AUC = 0.394; P = 0.135), histopathology (AUC = 0.459; P = 0.559), tumor diameter (AUC = 0.541; P = 0.559), gender (AUC = 0.476; P = 0.740), and age (AUC = 0.456; P = 0.534). ROC: Receiver operating characteristic; AJCC: American Joint Committee on Cancer; AUC: Area under the curve.
