Comparison of quantitative electroencephalography (qEEG)-information quantity (IQ) at different intervals by survival in all animals (A), first 4-hr postresuscitation intervals (B), by functional outcome (C) and 1 hr postresuscitation receiver operating characteristics (ROC) curve demonstrating the IQ value with optimal sensitivity and specificity for good neurological outcomes (D). (*p< .05, **p< .01, ***p< .001). Rats that died within 72 hrs postresuscitation had lower IQ values during the 72-hr experiment than survivors. Rats that died prematurely showed significantly lower IQ during each 30 min interval compared with an average of the first 4 hours (0.60±0.02, black line is MEAN and shadow is SEM in B) for survivors (p< .05). Rats with a bad functional outcome (Neurological Deficit Score (NDS) of <60) had significantly lower qEEG-IQ values in the course of 72 hrs than those with a good functional outcome (NDS of ≥60). A cutpoint of >0.523 yielded 81.8% sensitivity and 100% specificity for good outcomes, with an area under the ROC curve of 0.886.
