Outcome
- Type
- SECONDARY
- Title
- Clinical Global Impression - Improvement Scale (CGI-Improvement or CGI-I): Number of Subjects With Response (Much Improved or Very Much Improved) at Week 6
- Description
Number of subjects with improvement defined as CGI-I response of 1 (very much improved) or 2 (much improved). CGI-I is a single-item clinician rated scale used to assess global improvement in the subject's clinical state (bipolar mania) in response to study treatment and as compared to their status at pre-treatment baseline. Scores range from 1 (very much improved) to 4 (no change) to 7 (very much worse). Higher score = more affected.
