摘要: Objective To define the bronchodilator response (BDR) cutoff point that best identified asthma to determine frequency of abnormal spirometry results across severity. Study design Controller naive children were evaluated with clinical criteria alone establish a diagnosis and severity classification, then compared BDR, which was calculated as percent change from initial forced expiratory volume in 1 second. Receiver operator characteristic analysis determined for gave combination sensitivity specificity. Results Children (n = 346) 51 without asthma, aged 4 17 years, who met entry identified. The mean BDR asthmatics 8.6% (95% CI, 7.5-9.8), 2.2% 0.2-4.3) non-asthmatics (P Conclusion Spirometric include can potentially identify have clinically mild might benefit controller therapy.
