aBaseline lung function outcomes were defined as the first measurement within 31 days of receiving the FEV1 measurement device. Three of the included participants did not perform a baseline lung function measurement.
bICS: inhaled corticosteroids
cBeclomethasone or equivalent dose.
d(C-)ACT: (Childhood) Asthma Control Test.
eFEV1: forced expiratory volume in 1 second.
fFVC: forced vital capacity.
gFEF: forced expiratory flow.
