| Total sleep time, min | 465.7 (66.3) | 483.0 (67.8) | 461.4 (42.4) | 470.8 (35.3) | .55 |
| Fragmentation, min | 36.8 (9.0) | 36.3 (10.9) | 32.2 (7.2) | 33.3 (7.5) | .52 |
a
P values for the sleep parameters were based on paired t test comparing the mean change in the sleep parameter (baseline – treatment) for the 2 groups.
