Clinical Characteristics and Relationships with Sleep-related Impairment (N=100)

Characteristic	N (%) or Mean ± SD [Minimum-Maximum]	Statistics with Sleep-related Impairment
Stroke Type
Ischemic stroke	85 (85 %)	F_{(2, 97)} = .351, p = .705
Intraparenchymal hemorrhage	11 (11%)
Subarachnoid hemorrhage	4 (4%)
Current Antihypertensive Medication	70 (7%)	t₍₉₀₎ = 0.569, p = .571
Heart Failure	8 (8%)	t₍₉₈₎ = 0.960, p = .340
Diabetes	28 (28%)	t₍₉₈₎ = 0.278, p = .781
Depression (HRSD)	18.48 ± 3.12 [12.0–27.0]	r = 0.393, p = < .001
Currently Taking Antidepressant Medication	47 (47%)	t₍₉₈₎ = 2.05, p = .043
Severity of Stroke (NIHSS score)	3.43 ± 3.50 [0.0–15.0]	r = 0.021, p = .836
Functional Status (Barthel Index)	89.80 ± 19.89 [10.0–100.0]	r = − 0.151, p = .133
Fatigue (PROMIS Fatigue Scale)	56.22 ± 6.25 [41.9–72.9]	r = 0.618, p = < .001

Note. HRSD = Hamilton Rating Scale for Depression; NIHSS = National Institutes of Health Stroke Scale; PROMIS = Patient-Reported Outcomes Measurement Information System; Associations of clinical characteristics with sleep-related impairment were evaluated using Pearson correlations; Differences in sleep-related impairment by categories of clinical characteristics were evaluated using independent sample t-tests or analyses of variance.
