Patients' intraoperative data by acute kidney injury. Continuous data described as median (inter-quartile range). ACC, aortic cross-clamp; AKI, acute kidney injury; CPB, cardiopulmonary bypass; PFH, plasma-free haemoglobin.

| ACC duration (min) | 54 (34–90) | 44 (33–77) | 76.5 (42.25–102.25) | <0.001 |
| Blood priming of CPB, n (%) | 117 (65) | 64 (60.95) | 53 (71.62) | 0.14 |
