ROC curves. a FVC: Forced Vital Capacity (% predicted value); b PCF: Peak Cough Flow (L/min); c MIP: Maximum Inspiratory Pressure (cm H2O); d MEP: Maximum Expiratory Pressure (cm H2O); e SNIP: Sniff Nasal Inspiratory Pressure (cm H2O). The graphs are calculated with the values of the measurements of t = −3 as positive outcome and of t = −6 and t = −9 as negative outcome
