Incident disability after Year 4 by BMI variability quintile
| Quintile | ASV method | rASV method | ||
|---|---|---|---|---|
| HR (95% CI) | P | HR (95% CI) | P | |
| 1 | 1 (reference) | — | 1 (reference) | — |
| 2 | 1.20 (0.97, 1.47) | 0.09 | 1.19 (0.96, 1.47) | 0.11 |
| 3 | 1.25 (1.01, 1.5) | 0.04 | 1.17 (0.94, 1.45) | 0.17 |
| 4 | 1.56 (1.25, 1.939) | <0.01 | 1.23 (0.99, 1.53) | 0.06 |
| 5 | 1.36 (1.07, 1.72) | 0.01 | 1.38 (1.11, 1.72) | <0.01 |
Note: Those with higher BMI variability were more likely to experience incident disability by both the ASV and rASV methods. Abbreviations: ASV, average successive variability; BMI, body mass index; CI, confidence interval; HR, hazard ratio; rASV, residual average successive variability.
