Fig. 4

ROC curves for logistic regression models based on EEG and SSEP (upper row), and mixed models after adding ONSD on days 1, 2, and 3 (lower row). Left column shows ROC curves for the full data set, right column for the subset (after exclusion of patients with non-neurological cause of death). The red and green circles indicate the thresholds for predicting poor and good neurological outcome, respectively. AUC area under the curve, EEG electroencephalogram, ONSD optic nerve sheath diameter, SSEP somatosensory evoked potentials
