Whole blood aggregation results after activation with ADP or thrombin. The left panel shows dot-plots of whole blood platelet aggregation impedance per group for aggregation induced with ADP and thrombin. The right panel shows a CI plot where the type of induction is indicated on the y-axis and the ratios of averages (clopidogrel relative to control) and corresponding two-sided 95% CIs are presented on the x-axis. No bounded two-sided 95% CI for the ratio regarding ADP is available as the numerator of the ratio (i.e. mean of clopidrogel) is not statistically different from zero.
