SDXinsp changed significantly on the same day as CAT (1 day before AECOPD, both p=0.02) and earlier when using shorter running windows (3 days before AECOPD, p=0.01; accuracy=0.72 for 5-day windows).Conclusions SDXinsp from FOT telemonitoring reflects COPD symptoms and may be a sensitive biomarker for early detection of AECOPD.Telemonitoring of day-to-day variations in lung function using oscillometry in COPD may help assess symptoms and detect acute exacerbations early https://bit.ly/2RUhn7c ER -
