Fig. 3 Percentages of patients with angiographic no-reflow, by tertiles of von Willebrand factor (vWF) plasma levels on admission. Patients were divided into 3 groups according to tertiles of vWF plasma levels on admission, and the presence or absence of no-reflow was compared across groups (1st vs 2nd tertile, P < 0.01; 2nd vs 3rd tertile, P < 0.01; and 3rd vs 1st tertile, P < 0.01).
