Figure 3

Serum IL-5 levels according to the treatment status. The box & whisker plot shows the median and interquartile values of serum IL-5 levels. The median serum Il-5 values in patients on regular inhaled glucocorticoids and not on regular inhaled glucocorticoids were significantly higher compared to normal controls (p < 0.001 and < 0.002). There was no significant difference in the median serum IL-5 levels between asthmatics using and not using inhaled glucocorticoids (p = 0.69).
