Statistical correlation between the dose of prednisolone given to patients during initial 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 IVIG treatments to achieve remission; closed circles represent patients with EGPA (n = 8) who achieved remission after a single course of IVIG. Correlation coefficients (rs) were obtained by using Spearman’s rank correlation test.
