Results of multiple logistic regression analysis using all variables to predict continuous positive airway pressure adherence

	Coefficients	Std. error	OR	95% CI	p value
NREM-CT90(%)	−0.367	0.089	0.693	0.582–0.824	<.0001*

Dependent variable: 0 = good adherence 1 = poor adherence.

The significant variables were selected using multiple logistic regression analysis via the backward selection method.

NREM: non-rapid eye movement sleep, CT90: cumulative percentage of time spent at saturations below 90%; CI: confidence interval; OR: odds ratio.
