Diseases	Age <65 years (n=63)	Age ≥65 years (n=71)	p
COPD, n (row %)	9 (29)	22 (71)	<0.001
OHS, n (row %)	4 (31)	9 (69)
Kyphoscoliosis, n (row %)	7 (78)	2 (22)
Neuromuscular disease, n (row %)	24 (80)	6 (20)
HF and CVA, n (row %)	19 (37)	32 (63)

COPD: chronic obstructive pulmonary disease; OHS: obesity hypoventilation syndrome; HF and CVA: heart failure and cerebrovascular disease
