The results of the linear mixed-effects model predicting the degree of oxygen desaturation measured at arm muscle.

	Estimate (10−2)	95% CI (10−2)	t-Value	p-Value
Duration of event	2.33	[2.00, 2.66]	13.89	<0.0001
Mean HR within events	−1.49	[−2.14, −0.84]	−4.50	<0.0001
Per-hour AHI	0.12	[0.025, 0.22]	2.47	0.014

CI: Confidence interval. HR: Heart rate. Per-hour AHI is the number of apnea/hypopnea events divided by the sleep duration under each CPAP pressure per hour.
