Figure 2 Response Distribution to Clopidogrel

Normal distribution of the absolute change in 20-µmol/l adenosine diphosphate (ADP)-induced aggregation ( ${Delta}$ A). All of the patients under the double-headed arrow meet the definition for nonresponsiveness (NR). The distribution is shifted rightward in the 600-mg group indicating greater inhibition (responsiveness to clopidogrel). Reproduced with permission from the American College of Cardiology (72).
