Areas under the ROC curves of OHCA-BD and NULL-PLEASE scores for predicting brain death. The cutoff point of the OHCA-BD score to predict brain death was 20 points (sensitivity 67.5% and specificity 81.8%). Solid line, ROC curve of OHCA-BD score; dotted line, ROC curve of NULL-PLEASE score. ROC, receiver operating characteristic; OHCA-BD, out-of-hospital cardiac arrest-brain death
