Schematic map of principal component associations. Model of principal component associations and selected original variables with autoimmune manifestations. Red arrows mark significant positive correlations and green arrows significant negative correlations. Orange arrows represent significant associations of components with significant positive and negative loadings. The defining variables of the components are given in parentheses. Dotted lines and grey lettering mark borderline significance. The associations involving circulating serum amyloid P (SAP), endothelin-1 and insulin are not shown in the figure; please refer to Figure 2.
