Brief summary
The aims of this study are to (1) identify inflammatory/neurotrophic and neurodevelopmental markers that predict antidepressant response and suicidal risk in depressed youth and (2) predict their treatment response and the occurrence of suicidal events at the individual level using machine learning approach.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| the change from baseline in CDRS-R at week 8 or upon termination | baseline and 8 weeks or upon termination | The Children's Depression Rating Scale-Revised (CDRS-R) is a clinician-rated scale to measure the severity of depression of children and adolescents. The CDRS-R consists of 17 items. Depression symptoms are rated on a 5-point scale from 1 to 5 for sleep, appetite, and tempo of speech items and a 7-point scale from 1 to 7 for remaining 14 items. The total score ranges form 17 (normal) to 113 (severe depression). Change from baseline CDRS-R at 8 weeks or upon termination was calculated as baseline minus 8 weeks in the adjusted CDRS-R total score (CDRS-R total minus 17, the minimum possible total score). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| CGI-I at 8 weeks or upon termination | baseline and 8 weeks or upon termination | The Clinical Global Impression - Improvement scale (CGI-I) is a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention. and rated as: 1=very much improved; 2= much improved; 3=minimally improved; 4=no change from baseline; 5=minimally worse; 6=much worse; 7=very much worse since the initiation of treatment. CGI-I was measured at 8 weeks or upon termination |
