^*Adjusted for post-computed tomography and post-contrast acuity characteristics (Emergency department (ED) disposition to intensive care unit and ED diagnosis of acute myocardial infarction, sepsis or multi-organ failure).

CECT, contrast-enhanced computed tomography; CI, confidence interval; ESRD, end-stage renal disease.
