The examined major consequence was the distinction between the 2 teams within the MADRS rating between baseline and day 43, which was assessed by the centralized rater.
The principal secondary consequence was the change in MADRS rating between baseline and day 8. Other secondary outcomes included a distinction in rating on the Sheehan Disability Scale between baseline and day 43, the proportion of contributors that skilled sustained response to depressive signs, and sustained remission of depressive signs.
