This multicentre cross-sectional study included 93 children in total, 54 with problematic severe asthma and 39 age-matched with controlled asthma. Subjects completed the Paediatric Asthma Quality-of-Life Questionnaire as well as a standardized health questionnaire and the ACT. Objective measurements of exhaled nitric oxide, specific sensitization, pulmonary function and bronchial hyper-responsiveness to methacholine were also taken.
