The outcomes of the linear mixed-effects model of the decrease of StO2.

	Estimate (10–2)	95% CI (10–2)	t-value	P-value
Duration of events	1.96	[1.65, 2.27]	12.26	< 0.0001
Apnea–hypopnea	24.34	[9.64, 39.04]	3.25	0.0012
Mean HR within events	− 0.96	[− 1.61, − 0.31]	− 2.95	0.0032
Baseline StO2	− 5.30	[− 6.85, − 3.75]	− 6.71	< 0.0001
REM sleep–NREM sleep	− 24.04	[− 39.39, − 8.69]	− 3.07	0.0022
CPAP pressures	− 1.55	[− 2.55, − 0.55]	− 3.03	0.0025

Confidence interval (CI). Heart rate (HR). Rapid eye movement sleep (REM). Non-REM sleep (NREM). Continuous positive airway pressure (CPAP). The change in apnea is the reference for the change in hypopnea in this model. NREM sleep is the reference for REM sleep.
