This is the number of main rest intervals for which the sum of the quality score for in bed and out of bed times is 5 or 6. Bed times are given a reliability score between 1 and 3: -8 = Not Applicable, -1 = Flag/ Confusion, 0 = No Evidence of Sleep, 1 = Unreliable, 2 = Somewhat reliable, 3 = Mostly reliable

This is the number of valid main rest intervals in the recording that meet quality criteria. Main rest intervals are the intervals of time between the epoch at which the participant went to bed and the epoch at which the participant got out of bed, as marked by the scorer. It refers to the participant's nightly time in bed, including time awake and asleep.
