Receiver Operating Characteristic (ROC) curves for distinguishing VTE patients from healthy controls. The comparative ROC curves for all the three integrins (left) and t he combination of integrins (right) are provided. The area under the curve (AUC) of integrin β1, integrin β2 and integrin β3 was 0.875 (P=0.000, 95% CI: 0.829-0.922), 0.828 (P=0.000, 95% CI: 0.774-0.882), and 0.721 (P=0.000, 95% CI: 0.655-0.786), respectively, and that of combined three integrins was 0.915 (P=0.000, 95% CI: 0.876-0.954).
