Changes in the correlation coefficient between variables. a Changes in Spearman’s correlation coefficient according to the time course between the vasodilator-stimulated phosphoprotein-platelet reactivity index (VASP-PRI) and active metabolite concentrations (AM) measured at 30 min after the LD. b Changes in Spearman’s correlation coefficient according to the time course between the VASP-PRI and maximal platelet aggregation induced by 20 μM adenosine diphosphate (ADP). Blue lines and red lines represent the LD of prasugrel (20 mg) and that of clopidogrel (300 mg), respectively. *P < 0.05; **P < 0.01; ***P < 0.001
