Summary

This study aimed to see if measuring sertraline (Zoloft) levels in the blood and checking a specific gene (CYP2C19) could help doctors give the right dose to people with major depression. The goal was to reduce side effects and improve treatment. However, the study was withdrawn before enrolling any participants, so no results are available.
