From: Lung clearance index in adults with non-cystic fibrosis bronchiectasis
Receiver operating characteristic curves of lung clearance index and FEV 1 (% pred.) for distinguishing between control subjects and bronchiectasis patients. Receiver operating characteristic (ROC) curves are shown for lung clearance index (LCI) (Panel A) and forced expiratory volume in one second percent predicted (FEV1 [% pred.]) (Panel B). Areas under ROC curves are 0.90 for LCI and 0.83 for FEV1 (% pred.).
