Fig. 3From: HLA-B52 allele in giant cell arteritis may indicate diffuse large-vessel vasculitis formation: a retrospective studyPETVAS and the number of affected vessels in patients with newly diagnosed and untreated LVV. A, B PETVAS and the number of affected vessels in patients who were HLA-B52-positive (A) or HLA-B52-negative (B) with LVV were compared between the following three groups: TAK, UEOLVV without PMR, and LVV with GCA features. GCA, giant cell arteritis; HLA, human leucocyte antigen; LVV, large-vessel vasculitis; PETVAS, PET vascular activity score; PMR, polymyalgia rheumatica; TAK, Takayasu arteritis; UEOLVV, unclassified elderly onset LVVBack to article page
