The absolute counts of eosinophils were calculated from white blood cell counts and plotted against the prednisone dose at the time of sampling. a GPA and MPA both active and inactive samples are plotted and in a linear regression analysis the eosinophil counts in blood show a negative correlation with the prednisone dose (p = 0.008). b There was no correlation when the regression analysis was performed on only patients with active disease (BVAS3 ≥ 1, p = 0.27). c When the all patients were divided into three groups based on their prednisone dose, we only found a significant difference between the 0 mg/day group and the one with > 5 mg/day (p = 0.0007). Kruskal-Wallis test and Dunn’s multiple comparisons test was used to calculate the level of significance between the three groups
