Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
The primary efficacy analysis was conducted on the efficacyevaluable population, defined as all patients randomly assigned to a study group who received at least one dose of study medication and completed at least one postbaseline efficacy assessment.

Reporting Groups
  Description
Switch Group Participants will switch to aripiprazole.
Stay Group Participants will continue treatment with olanzapine, quetiapine, or risperidone.

There is NOT an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Open-label treatment is a limitation of this study, particularly for outcomes not measured in the laboratory but instead subject to clinical judgment.
