Prevalence of kidney organ failure on the last day of follow-up (‘standard-exposure’ group vs ‘high-exposure’ group)
| Standard-exposure group | High-exposure group | p Value | |
| Survivors and patients who had last creatinine measured >24 h before death | N=432 | N=438 | |
| Renal failure (*eGFR: ≤60 ml/min/1.73 m2) | 119 (27.6%) | 137 (31.3%) | 0.23 |
| Patients who died (with last creatinine measured within 24 h before death) | N=150 | N=145 | |
| Renal failure (eGFR: ≤60 ml/min/1.73 m2) | 105 (70.0%) | 99 (68.3%) | 0.83 |
| All patients with creatinine measurements | N=582 | N=583 | |
| Renal failure (eGFR: ≤60 ml/min/1.73 m2) | 224 (38.5%) | 236 (40.5%) | 0.51 |
↵* eGFR was assessed using the Cockcroft and Gault method (Ref: Cockcroft DW, Gault MH: Prediction of creatinine clearance from serum creatinine. Nephron 1976;16:31–41). Actual measured creatinin values were used.
eGFR, estimated glomerular filtration rate.
