Table 4. Multivariable logistic regression analysis for determinants of acute kidney injury (AKI).
| Characteristics | Odds Ratios (95%CI) | p |
|---|---|---|
| Age, years | 0.94 (0.90–0.99) | 0.016 |
| Intervention type, others vs. isolated CABG | 2.19 (1.07–4.47) | 0.031 |
| Glycemia, mg/dL | 0.99 (0.98–0.99) | 0.028 |
| eGFR, mL/min/1.73 m2 | 0.97 (0.96–0.99) | 0.007 |
| Blood pH, 1 unit decrease | 2.20 (1.22–3.97) | 0.008 |
| Time of ECCa, 10 min | 1.09 (1.01–1.18) | 0.028 |
| Time of Clampa, 10 min | 1.13 (1.02–1.26) | 0.021 |
atime of clamp and time of ECC have been added alternatively to the model due to multicollinearity (Variance Inflation Factor = 24.48). ECC, Extracorporeal Circulation; eGFR, estimated Glomerular Filtration Rate; CABG, Coronary Artery Bypass Surgery.
