The influence of ASA and clopidogrel on platelet adhesion. The main figures are representative examples of the variables constituting the respective factors. The insets show the Z-scores for each factor. Also shown in the insets are the comparisons between the control means of visit 1 and 2 and treatment with ASA (A), clopidogrel (C) and the combination of ASA and clopidogrel (A+C). The respective figures show the effect of platelet inhibiting treatment on ADP-induced adhesion (Factor 1, Fig A), ristocetin-induced adhesion to albumin (Factor 6, Fig B), LPA-induced adhesion to albumin (Factor 7, Fig C) and adhesion to collagen (Factor 8, Fig D) for patients (n = 29) and healthy controls (n = 29). All values are presented as mean + SEM. *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001, ns = not significant.
