Sleep Architecture and Periodic Limb Movements During Sleep (PLMS) According to Tanner Stage. Data Without Normal Distribution. Values are Displayed as Median (Range).
| Tanner Stage |
P value | |||||
|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 | ||
| Number of patients | 15 | 10 | 7 | 19 | 17 | |
| Sleep effi ciency (%) | 85.0 (71–94) | 86.0 (74–95) | 87.0 (66–92) | 89.0 (43–97) | 89.0 (56–98) | 0.719 |
| Sleep latency (minutes) | 19.0 (0–42) | 22.5 (3.5–76) | 14.0 (5.0–33.5) | 14.5 (1.0–83.5) | 16.5 (2.5–72.0) | 0.862 |
| REM latency (minutes) | 154.5 (60.5–267.0) | 102.0 (53–325) | 194.5 (133.5–329) | 136.5 (69.0–392.0) | 116.5 (44.5–287.0) | 0.106 |
| PLM index (N/hour) | 0.0 (0.0–7.2) | 0.0 (0.0–0.9) | 0.6 (0.0–2.4) | 0.2 (0.0–13.1) | 0.0 (0.0–4.1) | 0.025 |
REM, rapid eye movement; PLM, periodic limb movements.
No significant differences were observed between the different Tanner stages in regards to sleep effi ciency, sleep latency, and REM latency. There was a statistically signifi cant difference between the groups in regards to the PLM index. However, after adjusting the P value to account for the multiple pairwise comparisons none of the pairwise tests were statistically significant.
