Sleep characteristics of DMITRI subjects. Values are reported as mean (standard deviation). The number of nights analyzed is shown for each subject (“nights”). Analysis was performed on 48 subject-nights with ≥4 h of WSM data with sleep start and end times determined by WSM. Sufficient WSM data were not obtained for subjects 111 and 112, included in this table to report values for ESS (score).
