The risk of AKI between: 1) overall, 2) elderly patients (65 yr and older) and younger patients (younger than 65 yr), 3) men and women, 4) primary diagnoses such as trauma, sepsis, macrovascular disease, and cerebrovascular disease, 5) patients with chronic kidney disease (CKD) and without CKD, 6) admission to ICU and general ward, and 7) patients with organ dysfunction and without organ dysfunction was evaluated by propensity score-matched analysis.
