Sleep actigraphy following 6 weeks of high-pressure and high-intensity noninvasive ventilation

	High-pressure NIV (PSV)	High-intensity NIV (PCV)	Mean difference (95% CI)	P value
Actual sleep time (min)	345 ± 91	329 ± 120	16 (−49 to 82)	0.571
Actual wake time (min)	69 ± 35	83 ± 43	−14 (−40 to 11)	0.225
Sleep efficiency (%)	77 ± 12	73 ± 18	4 (−8 to 16)	0.484
Sleep latency (min)	20 ± 16	21 ± 16	−1 (−18 to 15)	0.835

Abbreviations: CI, confidence interval; PSV, pressure support ventilation; PCV, pressure controlled ventilation; NIV, noninvasive ventilation.
