Table 6. Results of multivariable logistic regression analysis including UDPB class 3–4 bleeding, chest tube output, transfusion and Hb decrease separately for postoperative AKI.
| Variable* | Odds ratio (95% CI) | P | |
|---|---|---|---|
| UDPB class 3–4 bleeding |  |
1.67 (1.32–2.10) | <0.001 |
| Chest tube output >1 L | 1.40 (1.08–1.83) | <0.001 | |
| Transfusion ≥5 U | 2.08 (1.38–3.16) | <0.001 | |
| Hb decrease > 50 g/L | 1.34 (1.14–1.58) | <0.001 | |
*, UDPB class 3–4 bleeding, chest tube output, transfusion and Hb decrease were separately included in the same multivariable logistic regression model which was composed of age, gender, BMI, diabetes, hypertension, prior MI, renal insufficiency, decreased LVEF, SBP values and preoperative haematocrit values. UDPB, universal definition of perioperative bleeding.
