1In this model, one non-vasculitis patient was removed because no vWF was recorded. 2Total sample size for this model is 41 observations on 17 patients. A+FN refers to the plasma concentration (μg/ml) of FN isoforms bearing the EIIIA segment. TFN refers to the total concentration (μg/ml) of FN in plasma. %A+ refers to the percentage of TFN comprised of A+FN isoforms. vWF and CRP respectively refer to the plasma concentrations of vWF and CRP, expressed as the % of the average value in healthy individuals.
