ANGPT2 and necrotizing vasculitis: However, Ang-2 levels were somewhat higher in the 26 samples associated with necrotizing vasculitis (1.6 [1.1;2.6] ng/ml) than in the 55 samples representing only non-vasculitic manifestations (1.1 [0.8;1.9] ng/ml; P = 0.03) or in the 54 samples reflecting remission (1.1 [0.9;1.4] ng/ml; P = 0.004).
