Eosinophils were an important parameter to assess disease activity and predict GI lesions in EGPA. Correlation of BVAS with eosinophil ratio (A) and count (B). Pearson correlation was calibrated for the analysis. (C) Receiver operating characteristic curve of eosinophil ratio for identifying patients with GI lesions in EGPA. AUC: area under the curve; BVAS, Birmingham Vasculitis Activity Score; EGPA, eosinophilic granulomatosis with polyangiitis; EOS, eosinophil; GI, gastrointestinal
