Patient demographics in those with anti-NMDAR encephalitis with and without extreme delta brush on EEG.
| EDB (n = 9) | No EDB (n = 12) | p-value | |
|---|---|---|---|
| Age, mean ± standard deviation | 22.9 ± 7.7 | 29.4 ± 14.5 | 0.24 |
| Female, n (%) | 8 (88.9) | 9 (75) | 0.60 |
| Teratoma present, n (%) | 4 (44.4) | 6 (50) | >0.99 |
| ICU admission, n (%) | 8 (88.9) | 4 (33.3) | 0.02 |
| Death, n (%) | 4 (44.4) | 0 (0) | 0.02 |
| Glasgow Outcome Scale score of 1–3 at 6 months, n (%)* | 7 (77.8) | 0 (0) | 0.002 |
| Glasgow Outcome Scale score of 4–5 at 6 months, n (%)* | 2 (22.2) | 9 (100) | |
| Number of EEGs obtained, mean ± standard deviation | 3.8 ± 1.5 | 2.5 ± 1.7 | 0.09 |

GOS is not reported for 3 patients as they are fewer than 6 months out from anti-NMDAR encephalitis diagnosis.
The bold values indicate statistically significant relationships as the p-values are less than 0.05.
