Clinical Global Impression (CGI)
Time Frame: 52 weeks
|
CGI is a 4-point scale that requires the investigators/subinvestigators to assess how much the subject's illness has improved or worsened relative to a baseline state.
Scores on the scale are rated as: 1, remission; 2, improved; 3, no change; 4, worsened
