- Cut-off values are presented as value (95% CI). The sensitivity and specificity are calculated with an ROC curve analysis. ALS Amyotrophic Lateral Sclerosis, HVS Home Ventilation Services, NIV Non-invasive ventilation, FVC Forced Vital Capacity (% predicted value), PCF Peak Cough Flow (L/min.), MIP and MEP Maximum Inspiratory and Expiratory Pressure (cm H2O), SNIP Sniff Nasal Inspiratory Pressure (cm H2O)
