Figure 1 Distribution of the response to (A) aspirin (assessed by 0.5 mg/ml arachidonic acid [AA]-induced platelet aggregation) and (B) clopidogrel (evaluated by change in 5 µmol/l adenosine diphosphate [ADP]-induced aggregation) from baseline to post-treatment. Both distributions were normal (p = 0.0003 and p = 0.01, respectively).
