parameters

These parameters are measured in this tool :

Total sleep (h): The total sleep time (in hour) is the total amount of sleep time scored during the total recording time.

Wake Time After Sleep Onset (WASO): is a statistic used in sleep studies to determine the amount of time a person spends awake, starting from when they first fall asleep to when they become fully awake and do not attempt to go back to sleep. The normal unit of measure for this statistic is minutes.

Sleep efficiency (SE) : is defined as the ratio of total sleep time to time in bed.

Sleep latency (m): is the length of time in minutes that it takes to accomplish the transition from full wakefulness to sleep.

The green regions: The green region in each plot represents the range of values within one standard deviation of the normal population measure.
