A predictive mortality score in ANCA-associated renal vasculitis

Several scores have been developed to predict mortality at anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) diagnosis. Their prognostic value in Caucasian patients with kidney involvement (AAV-GN) remains uncertain as none has been developed in this specific population. We aimed to propose a novel and more accurate score specific for them.
