Multivariable Cox proportional hazards model predicting index hospitalization/death1 from baseline gait speed assessment through December, 2011
| 2Adjusted hazard ratios (95% CI) | P value | |
| Gait speed/fall history | ||
| 3Faster walk/no fall history (reference) | 1 | |
| 4Slower walk/no fall history | 1.11 (0.79, 1.56) | 0.53 |
| Slower walk/fall history | 1.54 (1.04, 2.30) | 0.03 |
| Faster walk/fall history | 1.47 (1.05, 2.05) | 0.02 |
| CAD | 1.34 (1.01, 1.78) | 0.04 |
| Black race | 2.09 (1.48, 2.94) | < 0.001 |
| ESRD vintage, yr | 1.02 (1.00, 1.04) | 0.03 |
1Hospitalization events = 271; deaths = 17; 2Adjusted also for age, diabetes, CHF, CVA, PVD, other cardiac diseases, COPD, cancer, hemoglobin level, KDQOL-CF score, assistive device use;
3
Faster walk = gait speed ≥ 0.8 m/s;
4
Slower walk = gait speed < 0.8 m/s. ESRD: End-stage renal disease.
