Asthma score: percentage of days with score 0 (stable asthma), score 1 (mildly unstable asthma), and score 2 or more (minor or major deterioration). Data for weeks 21–24 were also used for the analysis of washout effects

	Weeks	Score = 0	Score = 1	Score = 2 or more
Placebo	0–24	77.4	20.4	2.3
	0–4	78.1	19.6	2.3
	21–24	78.4	20.6	1.0
	Washout 0–4	80.5	16.9	2.6
Salbutamol	0–24	76.5	20.8	2.7
	0–4	76.1	21.7	2.2
	21–24	77.1	20.0	2.9
	Washout 0–4	78.6	23.1	2.1
Salmeterol	0–24	87.4^7-150	11.9^7-150	0.6
	0–4	88.6	10.8	0.6
	21–24	88.6	11.0	0.4
	Washout 0–4	74.0^7-151	23.1^7-151	2.1

↵7-150 p = 0.001, salmeterol better than placebo.
↵7-151 p = 0.02, salmeterol worse than placebo.
