Trial Outcomes & Findings for Aripiprazole in Adolescents With Schizophrenia (NCT NCT00102063)

NCT ID: NCT00102063

Last Updated: 2012-08-10

Results Overview

Change from baseline to last observed post-baseline value in PANSS total score, using the last observation carried forward. This scale consists of symptom constructs (7 positive, 7 negative, 16 general psychopathology), each to be rated on a 7-point scale of severity with 1 being absent to 7 being extreme. Minimum score is 30 which is best outcome; maximum score is 210 for worse outcome.
