Figure 2

ROC curve of the angiogenesis factors in 52 AML patients at presentation and in 20 healthy controls. The white dots are the cut-off values between the patients and controls: vascular endothelial growth factor (VEGF)-A, 27.00 pg ml⁻¹; VEGF/PlGF, 5.87 pg ml⁻¹; VEGF-C, 664.20 pg ml⁻¹; Ang-1, 2556.46 pg ml⁻¹; Ang-2, 1039.77 pg ml⁻¹; and Tie-2, 11.48 ng ml⁻¹.
