Descriptive information of each objective sleep variable during full study period

Outcome measures	Overall M ± SD (range)	Weekdays M ± SD (range)	Weekends M ± SD (range)
TST	514.62 ± 86.50 min (253.00–820.00)	515.40 ± 81.87 min (294.50–800.00)	512.60 ± 98.19 min (253.00–820.00)
# Nighttime awakenings	37.81 ± 14.45 (0.00–83.00)	37.74 ± 14.56 (0.00–76.00)	38.00 ± 14.23 (0.00–83.00)
Onset latency	13.32 ± 16.04 min (0.00–106.00)	13.36 ± 15.82 min (0.00–84.50)	13.22 ± 16.72 min (0.00–106.00)
Blood glucose	197.11 ± 62.44 (80.67–428.33)	194.87 ± 61.14 (80.67–428.33)	215.16 ± 63.98 (95.20–432.00)

TST is the number of minutes between sleep onset and wake time minus time spent above the rest threshold during the night, onset latency is the minutes between going to bed and falling asleep, and number of nighttime awakenings indicate the number of bouts (i.e., continuous blocks of one or more epochs) where activity level was above the rest threshold during night. Information presented in this table describe each measurement during the full 7 day study period.

M mean; SD standard deviation; TST total sleep time.
