Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percentage of Participants That "Much Improved" (Score of 2) in, or "Completely Recovered" (Score of 1) From Their Irritability Severity, as Measured With the Clinical Global Impression-Improvement (CGI-I). | Collected weekly during the 8-week trial. The 8th-week outcome is reported. | A measure of change of irritability severity taking the baseline before randomization as a reference. Scores range 1 to 8, in which 1=Completely recovered,... 5=Unchanged,... 8=Much worse. Percentage of participants who responded are based on an estimation and might not match exactly with discrete numbers of participants based on the denominator. |
| Secondary | Irritability Severity at 8th Week of Trial. | Collected weekly during the 8th week trial. The 8th-week outcome is reported. | Clinical Global Impression-Severity (CGI-S): A measure of severity of irritability scale (from 1=Normal, not at all ill to 7=Among the most extremely ill patients). |
| Secondary | Functional Impairment at 8th Week of Trial | Collected weekly during the 8th week trial. The 8th-week outcome is reported. | Difference in functional impairment at 8th week of trial as measured with Children's Global Impression Scale (CGAS) with scores ranging from 1=Most impaired to 100=Not impaired at all. |
| Secondary | Depressive Symptoms at 8th Week of Trial | Collected weekly during the 8th week trial. The 8th-week outcome is reported. | Difference in depressive symptoms at 8th week of trial as measured with Children's Depression Rating Scale (CDRS) with scores ranging 17-113, where scores \>40 are considered over the clinical threshold, and scores \<28 are considered within the healthy range. |
| Secondary | Anxiety Symptoms at 8th Week of Trial | Collected weekly during the 8th week trial. The 8th-week outcome is reported. | Difference in anxiety symptoms at 8th week of trial as measured with the Pediatric Anxiety Rating Scale (PARS) with scores ranging 0-25. Higher values represent a worse outcome. |
