Baseline anthropometric and lung function data of study population (n = 37 children, 21 boys)
| Without relapse(n = 28) | With relapse(n = 9) | |
|---|---|---|
| ICS, inhaled corticosteroid; FEV1, forced expiratory volume in 1 second; FVC, forced vital capacity; PEF, peak expiratory flow; FENO, fractional nitric oxide concentration in exhaled air. | ||
| Data are given as mean (range) except for the dose of ICS which is given as median. FENO is given as geometric mean with 95% confidence interval. None of the items differed significantly between children with and without relapse. | ||
