Epworth Score	9.00 (4.50)	11.58 (5.24)	.005**

Note:

^†indicates that Levene’s test for equality of variances was significant (p < .05) and the adjusted p value is reported. The sample sizes varied due to missing data or “don’t know” responses. The available sample sizes were 137 for sleep efficiency, 141 for restless legs, 137 for dreams/nightmares, 140 for nocturnal sleeping hours, 142 for nocturia, 125 for snoring, and 141 for Epworth.
