Figure 1 Bleeding time (top) and ex vivo aggregation induced by 10 µmol/l of adenosine diphosphate (ADP) (bottom) at several time points of the experiment. P values refer to the effect of treatment on bleeding time and aggregation according to general linear model analysis of variance for repeated measures.
