|
Change From Baseline in Young Mania Rating Scale (Y-MRS) Total Score at Day 21
Time Frame: Baseline and Day 21
|
Y-MRS consists of responses to the following 11 items: elevated mood, increased motor activity energy, sexual interest, sleep, language-thought disorder, appearance, insight, irritability, speech - rate and amount, content and disruptive-aggressive behavior.
The scores from the 11 items are summed to give a total score ranging from 0 to 60, with a higher score indicating greater severity of symptoms.
The analysis is based on a mixed model repeated measures (MMRM) model.
An improvement in symptoms is represented by change from baseline values that are negative.
