Onset of relief of dyspnoea with budesonide/formoterol or salbutamol following methacholine-induced severe bronchoconstriction in adults with asthma: a double-blind, placebo-controlled study

Table 2 Methacholine provocation test data

Assessment	Budesonide/formoterol (n = 31)	Salbutamol (n = 31)	Placebo (n = 31)
FEV₁, L [range]
Before provocation	3.27 [1.78–4.93]	3.22 [1.83–4.98]	3.25 [1.83–5.11]
After provocation	2.14 [1.24–3.40]	1.99 [1.10–3.13]	2.03 [1.05–3.49]
PC₂₀, mg/ml [range]	0.42 [0.08–5.81]	0.44 [0.06–4.66]	0.46 [0.07–8.64]
Borg score^a after provocation [range]	3.03 [1.0–5.0]	3.31 [0.5–7.0]	3.50 [0.5–7.0]

All data are presented as geometric means, apart from Borg scores, which are arithmetic means.
^aBorg dyspnoea scores subjectively measure perceived breathlessness on a scale 0–10, where 0 = nothing at all and 10 = maximal breathlessness.
