Clinical Efficacy Based on Each Evaluation

	Reduction Rate of AE (n = 20)	Change in ACT From Baseline (n = 26)
Effective, n (%)	13 (65)	16 (62)
No change, n (%)	2 (10)	8 (31)*
Worsening, n (%)	5 (25)	2 (7)

Notes: Data are presented as n (%). The evaluations based on the reduction rate of AE were as follows: effective (≤ −50%), worsening (> 0%) and no change (other). The evaluations based on the change in ACT were as follows: effective (≥ 3), worsening (≤ −3) and no change (other). Of the 26 patients, we excluded six patients who had not experienced any AE. *Of the eight patients, four patients had 25 points in the ACT score without MCID.

Abbreviations: AE, acute exacerbations; ACT, Asthma Control Test; MCID, minimal clinically important difference.
