Text: Although the addition of NIPPV did not significantly improve the Chronic Respiratory Questionnaire compared to rehabilitation alone (mean difference in change between groups -1. 3 points (95 % CI : -9. 7 to 7. 4)), the addition of NIPPV did improve HRQoL assessed with the Maugeri Respiratory Failure questionnaire (-13. 4 % (-22. 7 to -4. 2 ; p = 0. 005)), mood state (Hospital Anxiety and Depression scale -4. 0 points (-7. 8 to 0. 0 ; p = 0. 05)), dyspnea (Medical Research Council -0. 4 points (-0. 8 to -0. 0 ; p = 0. 05)), daytime arterial blood gases (PaCO2 -0. 4 kPa (-0. 8 to -0. 2 ; p = 0. 01) ; PaO2 0. 8 kPa (0. 0 to 1. 5 ; p = 0. 03)), 6-minute walking distance (77. 3 m (46. 4 to 108. 0 ; p < 0. 001)), Groningen Activity and Restriction scale (-3. 8 points (-7. 4 to -0. 4 ; p = 0. 03)), and forced expiratory volume in 1 second (115 ml (19 to 211 ; p = 0. 019)).
