---|---|---|
Mean Change From the End of Phase A (Week 8 Visit) to Phase B (Week 14 Visit) in the Montgomery-Asberg Depression Rating Scale for the Efficacy Sample Set
Time Frame: Baseline and Week 14
|
The MADRS was utilized as the primary efficacy assessment of a participant's level of depression.
The MADRS consisted of 10 items, all rated on a 0 to 6 scale with 0 being the "best" rating and 6 being the "worst" rating.
The MADRS total score were to be unevaluable if less than 8 of the 10 items were recorded.
If 8 or 9 of the 10 items were recorded, the MADRS total score was the mean of the recorded items multiplied by 10 and then rounded of to the first decimal place.
The MADRS Total Score is the sum of ratings for all 10 items.
The possible total scores are from 0 to 60, with higher values indicating worse outcome.
