Spontaneous platelet aggregation in citrated whole blood after contact with the tested biomaterials assessed by scattering laser light forward and sideways (a.u.). The results shown represent the mean values and standard deviations (MEAN ± SD) of the percentage of aggregated platelets from four independent experiments with three replicates of each sample (n = 12). For negative and positive controls n = 48. Explanations of other symbols are in the text. Statistical significance levels are marked with asterisks as follows: *** p < 0.001, ns—not significant.
