  1. Comparison of time to discharge from the ICU and the hospital, and readmissions to the hospital within 3 months in patients with AKI according SCr criteria (AKI-SCr), according to UO only (AKI-UOelec′), and patients that did not have AKI by either criteria (non-AKI). The groups were also divided and compared according to the cut-off of above and below 70 years old
