	Placebo	Desipramine	p-value
V′_eupnoea L·min⁻¹	7.3 (1.6)	7 (1.3)	>0.5
V′_arousal L·min⁻¹	4.8 (1.9)	5.4 (2.3)	0.1
V′_0,active L·min⁻¹	2.5 (3.2)	4.0 (3.4)	0.33
V′_0,passive L·min⁻¹	0.7 (2.6)	1.0 (2.0)	0.39
V′_eupnoea− V′_arousal L·min⁻¹	2.7 (1.4)	1.8 (1.7)	0.07
V′_arousal−V′_0,active L·min⁻¹	2.1 (4.4)	0.6 (4.2)	0.33
V′_0,active−V′_0,passive (muscle compensation) L·min⁻¹	1.5 (2.9)	2.4 (3.7)	0.24

Data are presented data as median (interquartile range), unless otherwise stated. V′_eupnoea: eupnoeic ventilation; V′_arousal: ventilation that leads to arousals; V′_0,passive: ventilation at a nasal pressure of 0 cmH₂O when the pharyngeal muscles are passive; V_0,active: ventilation at a nasal pressure of 0 cmH₂O when the pharyngeal muscles are active.
