Receiver operating characteristic curves of diaphragm function indices predicting the frequency of AECOPD. The area under the curve (AUC) of the change of lung area during maximal deep breathing was 0.756. The AUC of chest wall motion during maximal deep breathing was 0.711. The diaphragmatic displacement during maximal deep breathing was 0. 833. The diaphragm thickening fraction during maximal deep breathing was 0.869. AECOPD, acute exacerbation of chronic obstructive pulmonary disease; AUC, area under the curve
