How Depression studies are organized in the registry
Most records use the formal term “major depressive disorder” or MDD rather than “depression” alone, and “treatment-resistant depression” (TRD) labels a distinct, sizable subset. The portfolio includes many behavioral, digital, and device interventions, so the intervention and study-type filters do real work here.
