Agreement between interpretation of annotations of the human expert (SM) and the SDA. Interpretation relates to summary statistics of the temporal evolution of seizures in each EEG recording. The average intra-class correlation coefficient (ICC) is presented and is estimated on the entire cohort of babies (N = 70). The summary statistics of seizures are estimated from the SDA annotation but only on babies who have seizure as detected by the human expert. The threshold that results in the highest ICC for each measure is shown. The SDA detects at least one seizure in 64, 54, 43, 38 babies at thresholds of 0.4, 0.5, 0.6, 0.7 respectively.
| Median | IQR | ICC | SDA threshold | |
|---|---|---|---|---|
| Seizure onset (h) | 15.1 | (7.7–32.5) | 0.722 | 0.4 |
| Seizure period (h) | 26.3 | (7.3–49.8) | 0.802 | 0.6 |
| Seizure burden (mins) | 81.1 | (26.6–181.3) | 0.859 | 0.5 |
| Seizure number (N) | 35 | (7–72) | 0.930 | 0.4 |
| Mean seizure duration (s) | 169 | (121–243) | 0.511 | 0.5 |
| Median seizure duration (s) | 124 | (92–146) | 0.323 | 0.7 |
