Platelet aggregation activity elicited by ADP or collagen. The number of patients in whom platelet aggregation activity is reduced are increasing in 1 week in both groups D and A. This finding is observed in the same tendency as for elicitation by ADP and collagen. Bubble size and the number indicate the number of patients. Y axis expresses the degree of platelet coagulation activity. Negative number indicates reduced activity and positive number indicates accelerated activity
