†
Transformations used in analyses. To facilitate interpretation, means (SDs) are raw values, represented in minutes. Sleep architecture outcomes include: %stage 1, 2, 3+4, and REM sleep. ANOVA results not reported for sleep architecture due to nonsignificant MANOVA.
+
Higher scores reflect greater movement during the sleep period (range 0-150).
