Similar to Aix, PWV showed positive correlations with the concentrations of VLDL (r = 0.41, p = 0.007), IDL-C (r = 0.4, p = 0.004), IDL-B (r = 0.35, p = 0.02) and LDL-1 (r = 0.31, p = 0.04) subfractions as well as with TG (r = 0.31, p = 0.04) in SLE. Here, PPIB is linked to systemic lupus erythematosus.
