Area under the ROC curve (C-index) for the prediction of poor neurologic recovery at each of the first 30 hours following intensive care unit (ICU) admission. These models included BIS scores and sedative requirements at each hour, in addition to the base model covariates age, time to return of spontaneous circulation, and initial rhythm of arrest. The optimal early prediction time occurred seven hours after ICU admission (C-index = 0.95, 95% CI: 0.91 – 0.99). The ROC curve for hour seven is shown.
