Asthma population	Patient number (N), [REF]	Allergen	Methacholine Mean PC20 mg/ml	Mean (SE) sputum Eos (%)	Correlation
Mild intermittent (recent diagnosis)	N = 30, [Boulet LP]	Cat, dog, house-dust mite or cockroach	4.9 (2.3)	0.9 (0.5–2.2)	NO
Mild intermittent (diagnosis > 5 years)	N = 30, [Boulet LP]	Cat, dog, house-dust mite or cockroach	2.9 (2.2)	0.9 (0.4–1.9)	NO
Mild persistent Off ICS treatment (6 month)	N = 30, [Foresi A]	House-dust mite	0.42 to 2.6 mmol	16.7 ± 5.06	YES r =-0.52
