LVV large-vessel vasculitis, AAV antineutrophil cytoplasmic antibody-associated vasculitis, IgAV IgA vasculitis and other small-vessel vasculitis, CRP C-reactive protein, PET/CT positron-emission tomography/computed tomography
Ap value across all the groups. Significant values expressed between the groups: aLVV vs. AAV, bLVV vs. IgAV, cAAV vs. IgAV
BHighest CRP value available closest to the diagnosis
CDiagnostic delay: timeline between the first contact to the tertiary health care and the date of vasculitis diagnosis
D12 months forward starting from the first contact to the tertiary health care
