CD62P P-selectin, CI confidence interval, sCD40L soluble CD40 ligand, SEM standard error of the mean
The β-coefficient represents the effect sizes from the regression analyses of the association between platelet characteristics induced by a given plasma sample and group status of the plasma donor. β-values represent the standardised regression coefficients
The t statistic (t) is the beta-coefficient divided by its standard error
