Associations of continuous eGFR with dual-talk cost gait domains derived using factor analysis
| Gait Domain | eGFR≥60, per 10-ml/min per 1.73 m2 Lower eGFR, n=193 | eGFR<60, per 10-ml/min per 1.73 m2 Lower eGFR, n=133 | Age, per 5-yr Older Age, n=326 | |||
|---|---|---|---|---|---|---|
| Coefficient (95% CI) | P Value | Coefficient (95% CI) | P Value | Coefficient (95% CI) | P Value | |
| Rhythm DTC | 0.1 (0.00 to 0.2) | 0.04 | −0.2 (−0.3 to −0.03) | 0.02 | −0.1 (−0.2 to 0.01) | 0.07 |
| Pace DTC | −0.04 (−0.2 to 0.1) | 0.58 | −0.01 (−0.1 to 0.1) | 0.83 | −0.03 (−0.1 to 0.1) | 0.60 |
| Variability DTC | 0.1 (−0.04 to 0.2) | 0.20 | −0.1 (−0.2 to 0.1) | 0.43 | 0.03 (−0.1 to 0.1) | 0.49 |
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; DTC, dual-task cost.
