Total sleep time during the study break in healthy controls (left) and participants with delayed sleep-wake phase disorder (DSWPD, right). Participants were permitted to sleep at any time on Thursday night to recover from study-induced sleep deprivation. After that, on Friday through Monday nights, participants were instructed to sleep within 30 minutes of their average prestudy sleep onset and wake times. The variability in total sleep time on Friday through Monday was significantly higher in the DSWPD participants versus healthy controls (p=0.012). The same symbols and colors are used for the same participants in the other figures.
