ROC analyses for (A) time to discontinuous aEEG background pattern (TTDC), (B) time to aEEG cycling (TTC), and (C) time to normalization (TTN) as a predictor of death or severe MRI brain injury. (D) Comparison of favorable versus adverse outcome frequency based on number of latency factors (0=TTDC, TTC, TTN all below cut point, 1–2 factors beyond cut point, or 3= TTDC, TTC, TTN all beyond cut point).
