Data represent number (percentage), average ± SD, or median (P10-P90), unless described otherwise.

These results were previously published [9, 10].

aFrom 7 days of actigraphy recording [9].

bAbsence of evening rise or daytime values >3 pg/mL in a 36-hour salivary melatonin collection [10].

cFrom 24-hour skin temperature measurements [10].

dAssessed with polysomnography.

ePercentage of total sleep time in which saturation was below 90%.

VFD, Visual field defects; TST, total sleep time; WASO, wake after sleep onset; PLM, period limb movements. Statistically significant differences are marked in bold.
