BMI, body mass index; ADL, activities of daily living; SD, standard deviation; HOT, home oxygen therapy; NPPV, noninvasive positive pressure ventilation; COPD, chronic obstructive pulmonary diseaseCOPD was the main cause of chronic respiratory failure in 13 patients (41.9%), followed by alveolar hypoventilation syndrome in 10 (32.3%), sequelae of pulmonary tuberculosis in six (19.4%), and scoliosis and spinal caries in one each. All patients were prescribed NPPV only at night during bedtime. Approximately half (n = 16, 51.6%) of the patients were on HOT. There were 19 past smokers (61.3%) and 30 current non-smokers (96.8%). Exactly 28 patients (90.3%) were living with family members, and 13 (41.9%) were using social resources. The mean use duration of NPPV and HOT was 3.0 (SD: 3.7) years and 2.0 (SD: 1.6) years, respectively. The P-ADL score was 169.5 (SD: 22.9) points. There were no significant differences in the characteristics of the participants between the intervention and control groups at enrollment.
