^*The response variable is given as “outcome”. The two predictors are vasculitis status and the marker shown at the beginning of the row. 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.
