Changes over time sleep continuity
| Time 1 | Time 2 | Time 3 | |
|---|---|---|---|
| Baseline: prior to chemotherapy (N = 26) | Approximately 3 weeks following last chemotherapy1 (N = 23) | Approximately 12 weeks following last treatment2 (N = 22) | |
| Sleep latency in minutes (SD) P=0.473# | 13.6 (11.9) | 12.2 (9.7) | 14.2 (13.6) |
| Wake-time after sleep onset in minutes (SD) P=0.234# | 62.2 (41.7) | 52.8 (22.5) | 64.5 (38.5) |
| Total sleep time in minutes (SD) P=0.043# | 396.7 (48.1) | 418.4a (26.6) | 401.1 (44.6) |
| Sleep efficiency (SD) P=0.161# | 84.1% (9.5) | 86.6% (4.6) | 83.6% (9.0) |
Notes:
1
One of the 23 patients had radiation therapy concurrent with chemotherapy and one patient had a surgical procedure following the completion of chemotherapy and prior to the second PSG assessment.
2
Following last chemotherapy or last radiation treatment if radiation therapy followed the conclusion of chemotherapy.
