Figure 6 shows the temporal distributions of the average depression periods, spreading depolarizations and isolated ictal epileptic events per recording day over the first 11 days after aneurismal SAH (Day 0 started with the time point of the initial haemorrhage).
The study is entitled as " Short- and long-term habituation… ", and indeed much space is dedicated to the description on how the recorded AEPs varied from one recording day to the next or from one experiment to the next.
One of the three EEG recordings was selected from each control subject (day 1, 2, or 3) according to the recording day of a corresponding age-matched patient.
On each recording day, males were removed after 1 h of recording, and females were left individually until the next recording day.
Recording day was found to have a small but significant positive effect on hand hygiene compliance.
Moreover, the total number of spreading depolarizations per recording day was significantly higher in patients with poor versus good outcome [3.1 (2.3 6.0) versus 1.2 (0.0 1.8) events per recording day, P = 0.017, n = 20, Mann Whitney rank sum test].
