Fig. 2From: Assessing tumor angiogenesis using dynamic contrast-enhanced integrated magnetic resonance-positron emission tomography in patients with non-small-cell lung cancerComparisons of serum VEGF-A, angiogenin, and angiopoietin-1 concentrations between non-small-cell lung carcinoma (NSCLC) patients and healthy controls. Serum (a) VEGF-A, (b) angiogenin, and (c) angiopoietin-1 concentrations in patients and healthy controls. P-values for statistical comparisons were obtained using the unpaired Student’s t-testBack to article page
