|---|---|---|
| acute kidney injury ≥ stage 2 according to the KDIGO criteria | According to the KDIGO criteria, postoperative acute kidney injury of stage 2 or higher was defined as a 100% increase in creatinine within the first seven days after surgery. The association between stage 2-3 acute kidney injury and postoperative body temperature trajectory classes was investigated. | seven days after valvular heart surgery |
| Measure | Description | Time Frame |
|---|---|---|
| non-recovery from acute kidney injury within 48 | The association between postoperative body temperature trajectory classes and non-recovery from acute kidney injury was investigated at two time points: within 48 hours | 72 hours after the onset of acute kidney injury |
