Table 1 Patient cohort characteristics. GPA: granulomatosis with polyangiitis, MPA: microscopic polyangiitis, IIF: indirect immunofluorescence of anti-neutrophil cytoplasmic antibodies, RTX: rituximab, CYC: cyclophosphamide, BVAS: Birmingham vasculitis activity score, GC: glucocorticoids, AZA: azathioprine, MTX: methotrexate, MMF: mycophenolate mofetil, COTRIM: trimethoprim/sulfomethoxazol, CRP: C-reactive protein in peripheral blood, eGFR: estimated glomerular filtration rate (MDRD formula), s.d.: standard deviation. Disease duration was defined as the period from initial diagnosis until study inclusion.
