Studies on predictors of mortality after AKI development
| Study | Indication/population | Design | AKI definition | Albumina (g L−1) |
|---|---|---|---|---|
| Chertow et al. [10] | ATN | Pb | ≥1.0 mg dL−1 SCr increase over 24–48 h | 27 |
| Obialo et al. [11] | Renal failure, ATN, or acute tubulointerstitial nephritis | R | ≥2.0 mg dL−1 SCr increase | 31 |
| Lins et al. [12] | Consecutive adults with AKI | P | SCr > 2 mg dL−1 or ≥50% increase | 32 |
| Dharan et al. [16] | Consecutive hospitalized patients with AKI | P | ≥0.5 or 1.0 mg dL−1 SCr increase if ≤1.9 or 2.0-4.9 mg dL−1 baseline, respectively | – |
| Mahajan et al. [19] | Consecutive ICU patients with AKI | R | >2 mg dL−1 SCr increase or 25% if CKD | – |
| Sezer et al. [20] | Hospital-diagnosed AKI | P | ≥1.5 mg dL−1 SCr increase within 48 h | 33.8 |
