Pre-treatment Bedtime Variability as Predictor of CPAP Non-Adherence (<4 Hours/Night) inMultivariate Logistic Regression(N=79)

Time	Variable	B Estimate	Standard Error	Χ²	p
One Week^a	Bedtime Variability (ln)^a	0.20	0.54	0.15	0.700
	Single Marital Status^b	0.68	0.26	6.89	0.009
One Month^b	Bedtime Variability (ln)^c	1.24	0.59	4.38	0.036
	Single Marital Status^d	0.73	0.27	7.53	0.006

Notes. CPAP= Continuous Positive Airway Pressure; ln= natural log
