Association of demographic and clinical characteristics with functional dependence

Characteristic	Model 1 OR (95% CI)	Model 2 OR (95% CI)	Model 3 OR (95% CI)
Age (per 10 year increase)	1.12 (0.89, 1.40)	1.05 (0.81, 1.36)	0.72 (0.49, 1.06)
Male sex (vs. female)	0.57 (0.28, 1.16)	0.65 (0.30, 1.41)	0.57 (0.23, 1.43)
Race
Black vs. white	2.05 (0.60, 7.07)	1.47 (0.38, 5.70)	1.82 (0.37, 8.96)
Other vs. white	0.82 (0.41, 1.63)	0.72 (0.32, 1.62)	0.58 (0.23, 1.50)
Stroke	6.65 (1.47, 30.09)	5.49 (1.14, 26.37)	5.89 (1.11, 31.10)
Cognitive impairment	2.77 (1.40, 5.48)	2.55 (1.23, 5.32)	2.95 (1.24, 7.00)
Systolic blood pressure (per 10 mmHg increase)	1.09 (0.96, 1.24)	–	1.25 (1.02, 1.54)
Diastolic blood pressure (per 10 mmHg increase)	0.92 (0.74, 1.16)	–	0.69 (0.47, 1.02)
Blood urea nitrogen (per 10 mg/dL increase)	0.86 (0.71, 1.03)	–	0.80 (0. 63, 1.00)

Model 1 is unadjusted. Model 2 is adjusted for age, sex, race, stroke, and cognitive impairment. Model 3 is adjusted for age, sex, race, stroke, cognitive impairment, systolic blood pressure, diastolic blood pressure, and blood urea nitrogen.

CI = confidence interval; OR = odds ratio.
