Table 4– Sleep measurements during the multiple sleep latency tests in obstructive sleep apnoea (OSA) patients with residual excessive sleepiness (RES) compared with patients without RES and healthy controls

Characteristic	OSA with RES	OSA without RES	Healthy controls	p-value
Patients n	20	20	20
Sleep latency min	12.2±0.9*^,#	15.8±0.9	15.7±1.0	0.006
Mean sleep latency <8 min	10.0	5.0	10.0	0.84
Mean sleep latency <10 min	40.0*^,#	10.0	10.0	0.04
SOREMPs	0.6±0.9*^,#	0.1±0.2	0.1±0.4	0.01

Data are presented as mean±se or %, unless otherwise stated. SOREMP: sleep onset in rapid eye movement period. *: p<0.05 for OSA patients with RES versus without RES; ^#: p<0.05 for OSA patients with RES versus healthy controls.
