TST was defined as the total amount of time in minutes that was actually spent sleeping the previous night as recorded daily in the participant's sleep diary. TST values over the 6 week In-Treatment Period were averaged for each participant, and average TST was then reported by treatment arm. For participants with missing data, the average of the nights for which TST data were available was used in the analysis.
