Statistical correlation between the number of eosinophils in the peripheral blood before IVIG treatment and (a) the percentage of FOXP3+CD4+T cells or (b) the ratio of the percentage of FOXP3+CD4+T cells before the initial IVIG treatment to that at 1 month thereafter. Open circles represent patients with EGPA (n = 9) who needed two or more courses of IVIG to achieve remission; closed circles represent patients with EGPA (n = 8) who achieved remission after a single round of IVIG. Correlation coefficients (r) were obtained by using Spearman’s rank correlation test.
