Fig. 3From: Effects of treatment with corticosteroids on human rhinovirus-induced asthma exacerbations in pediatric inpatients: a prospective observational studyComparison of changes in FEV1% predicted from baseline in HRV-positive patients. Eighteen HRV-positive patients underwent a PFT 3 months after exacerbations, and FEV1% predicted from baseline was compared with the treatment period of systemic corticosteroids (3–5 days, n = 8; 6–8 days, n = 10). Values are expressed as the median with an interquartile range. Differences in data were analyzed by the Mann–Whitney U-test. FEV1, forced expiratory volume in 1 secondBack to article page
