—Adjusted Odds Ratios for Adequate Initial Adherence to CPAP (n = 117)

Variable	Adjusted OR (95% CI)	P Value
Lipid medication adherence ≥ 80% ;(vs < 80%)a	1.8 (1.0-3.3)	.04
Age (per 10-y increase)	1.3 (0.9-1.6)	.13
Race, black (vs white/other)b	0.8 (0.5-1.5)	.55
BMI (per SD change)	0.8 (0.6-1.0)	.10
Epworth Sleepiness Score (per SD change)	1.1 (0.9-1.5)	.41
Apnea-hypopnea index (per SD change)	1.0 (0.8-1.3)	.91
Diagnostic sleep study, unattended (vs in-laboratory)	1.2 (0.7-2.1)	.44
First night of CPAP use (vs subsequent nights)	0.4 (0.3-0.6)	< .001

OR = odds ratio. See Table 1 for expansion of other abbreviation.

^aPharmacy refill adherence is measured as the percent of d covered with a lipid-lowering medication, calculated as the number of d covered divided by the total number of d on drug therapy during the exposure window in the year before CPAP initiation.

^bOther race category consists of Pacific Islander, Asian, and Indian American (n = 5), and race classification missing (n = 4).
