BETA COEFFICIENTS AND P VALUES FOR UNADJUSTED AND ADJUSTED PREDICTION MODELS BASED ON CORRELATIONS BETWEEN MEAN SLEEP SaO2 AND THE PRIMARY OUTCOME MEASURE

	Outcome Measure: Cerebrovascular CO2 Reactivity (cm/s/mm Hg PETCO2)
	Model 1		Model 2		Model 3
	Unadjusted		Adjusted for age, sex, body mass index, waist:hip ratio, current smoking, drinks per week, diabetes		Adjusted (Model 2 adjustments + increase in MAP)
