For the AAV group, neither myeloperoxidase (MPO) or proteinase-3 (PR3) ANCA levels (rho = 0.09, p = 0.63 and rho = −0.035, p = 0.85, respectively) nor the Birmingham Vasculitis Activity Score (BVAS) (rho = 0.017, p = 0.93) significantly correlated with anti-oxLDL antibody levels. Here, MPO is linked to vasculitis.
