CI = confidence interval, ACT-auto = actigraphy automatically scored by the software program, ACT-human = human-adjusted actigraphy scoring, SE = sleep efficiency, TST = total sleep time, TST-DS = duration of deep sleep, TST-LS = duration of light sleep, TST-RS = duration of REM sleep, WASO = wake after sleep onset.
