Comparison of potential predictors according to restart within 90 days or not
| No restart of RRT (n = 58) | Restart of RRT(n = 32) | p value | |
|---|---|---|---|
| Study variables | |||
| Day 2 urinary NGAL (n = 90), ng/mL | 277 (51–670) | 776 (245–1,921) | 0.005 |
| Day 2 urine output (n = 81), L | 2.503 (l.231) | 1.783 (1.263) | 0.015 |
| Day 2/0 incremental creatinine ratio (n = 81) | 1.26 (1.01–1.46) | 1.64 (1.52–1.75) | <0.001 |
| Confounders | |||
| Day 2 nonrenal SOFA (n = 82) | 4 (2–6) | 5 (3) | 0.883 |
| Preadmission eGFR (CKD-EPI;n = 85), mL/min/1.73 m2 | 67.1 (25.4) | 69.0 (41.2–91.7) | 0.754 |
Median (25th–75th percentile) for continuous variables, number (percentage) when appropriate.
NGAL is expressed in ng/mL.
RRT, renal replacement therapy; NGAL, neutrophil gelatinase-associated lipocalin; SOFA, sequential organ failure assessment; eGFR, estimated glomerular filtration rate; CKD-EPI, chronic kidney disease-epidemiology collaboration.
