Effect of HFA-BDP MDI ETN on nasal polyp score and sinus CT findings. Nasal polyp score (A) and sinus CT score (B) were evaluated before (visit 1) and 4 weeks after treatment (visit 2). Individual values and means of 12 patients in the placebo group (P; A [i]) and 11 patients in the HFA-BDP group (H; B [i]) are shown. ^#P < 0.05, ^##P < 0.01 (vs. visit 1). Changes from visit 1 to visit 2 were also compared between two groups (A [ii] and B [ii]). Data represent mean ± standard deviation. ^*P < 0.05, ^**P < 0.01 (vs. placebo).
