Table 3.

Predicted recovery sleep dose at which sleep-restricted subjects would intersect the levels of neurobehavioral function of control subjects on each outcome.

	Time in Bed intersection with control group		Total Sleep Time intersection with control group
	Intersection (h)	CI (h)	Intersection (h)	CI (h)
PVT lapses	10.66	7.97-13.34	10.00	7.32-12.68
KSS score	10.62	7.80-13.44	10.29	7.10-13.51
MWT sleep latency	15.16	10.41-19.90	15.76	10.10-21.44
DSST # correct	8.07	5.99-10.15	7.69	5.45-9.93
PVT fastest 10%	13.09	8.64-17.54	11.75	7.75-15.75
POMS fatigue	8.95	4.95-12.96	8.32	4.47-14.18

Intersection (h) refers to the projected recovery sleep time at which the linear model (fit to the sleep dose adjusted means from the ANCOVA analyses) intersects with the non-sleep-restricted control group (10 h TIB/night) for each outcome. CI (h), 95% confidence intervals on the intersection points. PVT lapses, Psychomotor Vigilance Test number of lapses; KSS, Karolinska Sleepiness Scale scores; MWT, Maintenance of Wakefulness Test sleep latency; DSST, Digit Symbol Substitution Task number correct, PVTf10, Psychomotor Vigilance Test fastest 10% of reaction times; POMSf, Profile of Mood States fatigue subscale.
