Table 3.
Comparison of the trajectory summary metrics for models using features from only QS, only non-QS, QS and non-QS, and non-specific two-hour periods of EEG containing at least one full sleep cycle.
| QS* | non-QS* | QS & non-QS* | full-cycle | ||
|---|---|---|---|---|---|
| RMSE (weeks) | normal | 0.85 (0.61–1.45) | 0.86 (0.69–1.23) | 0.76 (0.62–1.43) | 0.75 (0.56–1.32) |
| abnormal | 1.36 (1.00–1.79) | 1.40 (1.08–1.84) | 1.36 (1.17–1.55) | 1.23 (0.90–1.43) | |
| difference | 0.51 | 0.54 | 0.61 | 0.48 | |
| Cliff’s Delta | 0.38 | 0.43 | 0.41 | 0.32 | |
| δmax (weeks) | normal | 1.00 (0.75–1.91) | 1.14 (0.89–1.88) | 0.93 (0.78–1.64) | 1.05 (0.74–1.79) |
| abnormal | 1.90 (0.87–2.75) | 2.01 (1.44–3.15) | 1.80 (1.20–2.85) | 1.69 (0.98–2.43) | |
| difference | 0.90 | 0.87 | 0.87 | 0.64 | |
| Cliff’s Delta | 0.21 | 0.39 | 0.40 | 0.30 |
Values for the normal and abnormal outcome trajectories are both given, with medians and the interquartile ranges (in brackets) provided (where appropriate). Differences between these values are also given, along with the Cliff’s delta. The results are presented at values of Nf within each significant cluster where the differences were maximal. Asterisks in the column headings denote that the results were part of a statistically significant cluster.
