e-Diary spirometer compliance in two pharmaceutical trials

This study examined compliance with the Vitalograph In2itive e-diary for recording domiciliary diary scores and lung function testing in adult and pediatric asthma patients participating in two separate but otherwise identical clinical trials; one trial included 546 adult patients aged 18–65 years, while the other included 452 pediatric patients aged 4–16 years. Each morning and evening before taking any medication, patients in both trials were required to use the device to record information about their symptoms and to measure pulmonary function (FEV1 and PEF).
