Age at diagnosis and risk of relapse in antineutrophil cytoplasmic antibody-associated vasculitides (AAV), in relation to lead human leucocyte antigen (HLA) variants. The number of risk alleles per patient of HLA-DPB1*04:01 and HLA-DRB1*04:04 was analysed for associations with age at diagnosis of proteinase 3 (PR3)-AAV (A) and myeloperoxidase (MPO)-AAV (B), respectively, and were plotted using Kaplan-Meier curves. Full, dashed and dotted lines correspond to the presence of 0, 1 or 2 risk alleles per patient.
