Mortality rates (%) in Acute Kidney Injury (AKI) vs no Acute Kidney Injury according to different algorithms, in the entire cohort and in ICU survivors separately. a: Mortality rates at ICU, 3 months, 1 year and 2 years in the entire cohort in AKI vs no AKI, either based on ΔADM > 0.3 mg/dl, ΔHIS > 0.3 mg/dl or ΔEST > 0.3 mg/dl. Only based on ΔADM > 0.3 mg/dl, there is a higher mortality at ICU, 3 months and 1 year in AKI vs no AKI. At year 2, there is no significant different in mortality between AKI and no AKI with either of the algorithms. b: Mortality rates at 3 months, 1 year and 2 years in ICU survivors in AKI vs no AKI, either based on ΔADM > 0.3 mg/dl, ΔHIS > 0.3 mg/dl or ΔEST > 0.3 mg/dl. There is no significant difference in mortality between AKI and no AKI at the three time points, independent of the algorithm used
