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

Figure 2 Kaplan-Meier curves for postoperative survival. A: The median survival time of patients with positive CD73 was shorter than that of patients with negative CD73 (log-rank test: P < 0.001); B: Hypoxia-inducible factor-1α (HIF-1α) expression had no correlation with the survival time of patients (log-rank test: P = 0.103); C: There was a significant difference among groups stratified according to CD73/HIF-1α expression (P < 0.001). Patients with CD73+/HIF-1α+ had the worst prognosis.
