Table 1.
Row mean values (M) and standard deviations (SD) for the various actigraphic parameters recorded during the whole recording period (i.e., 28 days), accompanied by their cutoff values.
| M (SD) | Cutoff valuesa | |
|---|---|---|
| SE | 85.48 (7.98) | >87 |
| FI | 44.15 (16.80) | <35 |
| SOL | 10 (7) | <14 |
| WASO | 54 (33) | <40 |
| TST | 404.96 (51.98) | NA |
Note. SE = sleep efficiency; FI = fragmentation index; SOL = sleep onset latency; WASO = wake after sleep onset; TST = total sleep time; NA = not available.

The cutoff values were originally proposed by Natale et al. (2014) to discriminate patients with primary insomnia from healthy controls. No specifically developed cutoff values for patients with narcolepsy type 1 are currently available.
