Figure 1From: Incidence and outcome of contrast-associated acute kidney injury assessed with Risk, Injury, Failure, Loss, and End-stage kidney disease (RIFLE) criteria in critically ill patients of medical and surgical intensive care units: a retrospective studyThe ROC curve of the APACHE II score. AUC (predicted probability of APACHE II score to the CA-AKI) was 0.63 (95% CI: 0.54ā0.71, pā=ā0.004, Ń statistic). Cut-off value of APACHE II score was below 17. ROCā=āreceiver operating characteristic, APACHE IIā=āAcute Physiology and Chronic Health Evaluation II, AUCā=āarea under ROC curve, CA-AKIā=ācontrast-associated acute kidney injury, CIā=āconfidence interval, pā=āprobability value, Cut-off value of APACHE II scoreā>ā17.Back to article page
