Figure 1. Lower delta power during quiet sleep is associated with worse neurologic examination scores.

Figure 1

On the EEG, lower delta frequency power (0.5–4 Hz) during quiet sleep was associated with worse neurologic examination (Thompson) scores (Spearman correlation p < 0.05, open circles). The EEG power at higher frequencies did not correlate with examination scores (p > 0.05, crosses).
