Statistical correlation between the dose of prednisolone during the initial IVIG treatment and the serum IgG level in 16 EGPA patients (one patient did not measure serum IgG). 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 = 7) who achieved remission after a single course of IVIG. Correlation coefficients (rs) were obtained by using Spearman’s rank correlation test.
