Definition of abbreviations: BMI = body mass index; FEF25–75% = forced expiratory flow, midexpiratory phase; PC20 = provocative concentration of methacholine causing a 20% fall in FEV1; PEF = peak expiratory flow.
Percentage predicted values were calculated using data from Hankinson and colleagues (54).
