Predictive value of the electroencephalogram (EEG) as a function of time after cardiac arrest. "Corrected" values follow from the mixed model, which accounts for the sensitivity and specificity at the 8 time points being calculated from different, partially overlapping groups of patients. Error bars indicate 95% confidence intervals. Numbers (N) refer to the total number of patients with an EEG epoch available at the indicated time point. (A) Test characteristics for the prediction of poor outcome based on “suppression” or “synchronous pattern with ≥50% suppression.” (B) Test characteristics for the prediction of good outcome based on "continuous" EEG pattern.
