Associations of continuous eGFR with walking-while-talking gait domains derived using factor analysis

Gait Domain	eGFR≥60, per 10-ml/min per 1.73 m2 Lower eGFR, n=196		eGFR<60, per 10-ml/min per 1.73 m2 Lower eGFR, n=134		Age, per 5-yr Older Age, n=330
	Coefficient (95% CI)	P Value	Coefficient (95% CI)	P Value	Coefficient (95% CI)	P Value
Rhythm	0.1 (−0.01 to 0.2)	0.08	−0.2 (−0.3 to −0.1)	<0.001	−0.2 (−0.3 to −0.2)	<0.001
Pace	−0.04 (−0.2 to 0.1)	0.50	−0.01 (−0.1 to 0.1)	0.84	−0.1 (−0.2 to 0.02)	0.12
Variability	0.1 (−0.05 to 0.2)	0.23	−0.04 (−0.2 to 0.1)	0.52	0.1 (−0.02 to 0.2)	0.13

Multivariable linear regression adjusting for age, sex, race, education, body mass index, neuropathy, number of comorbidities, and number of medications was performed. Linear splines for eGFR were constructed with knot placed at 60 ml/min per 1.73 m². 95% CI, 95% confidence interval.
