A total of 2954 patients with complete clinical data were included in this study. Receiver operating characteristic (ROC) curves were used to analyze and evaluate the predictive effects of the four scoring systems on the 28-day mortality risk of AKI patients and each subgroup. The best cutoff value was identified by the highest combined sensitivity and specifRenal failure320-328https://www.ebi.ac.uk/biostudies/studies/S-EPMC8856098biostudies-literatureThe predictive value of the Oxford Acute Severity of Illness Score for clinical outcomes in patients with acute kidney injury.PMC8856098Wang MXi XWang NJiang LDu BZhu BfalseThe predictive value of the Oxford Acute Severity of Illness Score for clinical outcomes in patients with acute kidney injury.<h4>Objective</h4>To compare the performance of the Oxford Acute Severity of Illness Score (OASIS), the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, the Simplified Acute Physiology Score II (SAPS II), and the Sequential Organ Failure Assessment (SOFA) score in predicting 28-day mortality in acute kidney injury (AKI) patients.<h4>Methods</h4>Data were extracted from the Beijing Acute Kidney Injury Trial (BAKIT).
