Values are presented as mean ± SD unless otherwise indicated. One-way analysis of variance was used for group comparisons unless otherwise indicated. aIn patients < 18 years, a modified ESS version was used. bKruskal-Wallis analysis of variance. ESS = Epworth Sleepiness Scale, MSLT = Multiple Sleep Latency Test, ns = not significant, REM = rapid eye movement, SD = standard deviation, SOREMPs = sleep-onset REM sleep periods.
