Open circles represent patients with EGPA (n = 8) who achieved remission after a single round of IVIG treatment; open squares represent patients with EGPA (n = 9) that required multiple courses of IVIG to achieve remission. The mean values for each patient group were compared by using the Wilcoxon matched-pairs t-test; P < 0.05 was considered statistically significant. NS, not significant.Back to article page
