Table 3.

Cox-regression analyses according to reported acetylsalicylic acid intake. Regression models: A—unadjusted; B—adjusted for age and sex. Abbreviations: aspirin, acetylsalicylic acid; 95%CI, 95% confidence interval; HR, hazard ratio. Classification limits of plasma soluble P-selectin: median (acetylsalicylic acid, yes) = 125.11 ng/mL, median (acetylsalicylic acid, no) = 91.88 ng/mL. *p < 0.05, **p < 0.01, ***p < 0.001
