TableJSON Schema

| sex | Yes | Patient's biological sex. Use 'ALL' to include studies regardless of sex restrictions. | |
| conditions | Yes | Medical conditions or diagnoses. E.g., ["Type 2 Diabetes", "Hypertension"]. Plain words only — reserved chars `[ ] ( ) ,` inside an entry will fail. | |
| location | Yes | Patient location as `{ country (required), state?, city? }`. Country is required; state/city narrow the match. For radius-based geographic search, use clinicaltrials_search_studies with geoFilter. | |
