Figure 2. Superiority of mepolizumab over placebo in patients with L-HES.
The response rate of patients with L-HES to mepolizumab versus placebo is shown; white bars represent the mepolizumab treatment arm, and hatched bars represent the placebo treatment arm. PDN: prednisone. * p-values <0.05, ** p-values < 0.005. Note: for PDN 0 mg until end of study, two-sided p-value is 0.07 and one-sided p-value is 0.049 using Fischer’s Exact test.
