Length of stay and proportion of patients discharged in the Rule Out Myocardial Infarction/Ischemia Using Computer Assisted Tomography II trial. The cumulative frequency of discharges from the index visit according to the length of stay is shown. The horizontal line indicates the median length of stay in the two study groups, which was significantly different (8.6 h in the coronary computed tomography angiography vs. 26.7 h in the standard-evaluation group, P < 0.001).
