  1. Data were presented as number of patients (percentage) or mean (95% confidence interval)
  2. ICU Intensive care unit, MV Mechanical ventilation
  3. a Defined as increase in serum creatinine by ≥26.5 μmol/l within 48 h; or increase in serum creatinine to ≥1.5 times baseline, which is known or presumed to have occurred within the prior 7 days; or urine volume < 0.5 ml/kg/h for 6 h. Stage 1 was defined as serum creatinine 1.5–1.9 times baseline or ≥ 26.5 μmol/l increase or urine output < 0.5 ml/kg/h for 6–12 h; stage 2 was defined as serum creatinine 2.0–2.9 times baseline or urine output < 0.5 ml/kg/h for ≥12 h; stage 3 was defined as serum creatinine 3 times baseline or increase to ≥353.6 μmol/l or initiation of renal replacement therapy or urine output < 0.3 ml/kg/h ≥ 24 h or anuria ≥12 h
  4. b Requirement of vasopressors (norepinephrine or epinephrine) to maintain systolic blood pressure ≥ 90 mmHg after surgery
  5. c Results of patients who required vasopressors after surgery
  6. d Results of patients who required mechanical ventilation in the ICU after surgery
  7. e Results of patients who were admitted to the ICU after surgery
