Association of pre-ESRD weight change with mortality within 1 year after dialysis initiation
| Change in Weight before Dialysis Initiation | Crude 1-Yr Mortality Rate N (%) | Unadjusted HR (95% CI) | Adjusted HRa (95% CI) |
|---|---|---|---|
| Quintile 1 (−59% to −15%) | 1286 (58.3) | 1.28 (1.18 to 1.38) | 1.35 (1.25 to 1.47) |
| Quintile 2 (−14% to −9%) | 1189 (53.4) | 1.10 (1.02 to 1.20) | 1.07 (1.00 to 1.17) |
| Quintile 3 (−8% to −4%) | 1198 (53.9) | 1.10 (1.01 to 1.19) | 1.07 (0.99 to 1.16) |
| Quintile 4 (−3 to –3%) | 1112 (50.1) | 1.00 (reference) | 1.00 (reference) |
| Quintile 5 (4% to 58%) | 1278 (57.6) | 1.24 (1.14 to 1.34) | 1.24 (1.14 to 1.35) |
Pre-ESRD weight was measured a median of 4.7 months before dialysis initiation. HR, hazard ratio; CI, confidence interval.
