How we selected and connected these records

Selected registered studies with an overall status of Recruiting or Not yet recruiting and at least one England location established by postcode, recorded nation, or source coordinates within the ONS December 2024 boundary. Retained structured fields; omitted descriptions, eligibility text, contacts and non-England locations. Deduplicated identical locations. Linked local care areas only by exact postcode geography. Location points are used for nation filtering, not directions or facility matching.
