Coverage · what the dataset can prove
Coverage is the public checklist for evaluating a pack before purchase: exported records, active sources, field groups, workflow fit, and the caveats that limit interpretation.
Record coverage
The public counts below come from export-ready records and the source registry. They update with every snapshot cut instead of being hand-maintained in website copy.
Canonical trial rows in the current dated release; this is not an upstream registry total.
Distinct exported canonical trials with an active ClinicalTrials.gov source contribution in the measured release.
Distinct exported canonical trials with an active EU CTIS source contribution in the measured release.
Distinct exported canonical trials with an active EU Clinical Trials Register source contribution in the measured release.
Distinct exported canonical trials with an active ISRCTN source contribution in the measured release.
Distinct exported canonical trials with an active DRKS contribution admitted by the registered-from-2025 or last-updated-in-2025 licence gate.
Maximum age 8 days. Oldest measured source refresh: 2026-11-02.
Weekly publication requires complete evidence no more than eight days old for four full registry crawls, the licensed DRKS slice, Health Canada CTD, and exact-edge PubMed.
Field coverage
Schema groups come from the exported field model and curated field highlights. They are the default coverage map for filtering, joining, and reviewer audit work.
| group | fields | examples |
|---|---|---|
| Identity and registry | 5 | id, primary_registry, registry_id, source_record_url |
| Titles and summaries | 3 | brief_title, official_title, brief_summary |
| Status and design | 6 | overall_status, phase, study_type, primary_purpose |
| Sponsor | 2 | sponsor_name, sponsor_class |
| Enrollment and dates | 4 | start_date, completion_date, enrollment_count, primary_completion_date |
| Provenance | 1 | _provenance |
| Conditions and interventions | 5 | lead_condition, conditions, interventions, intervention_types |
| Outcomes and publications | 3 | outcomes, outputs, publications |
| Regulatory | 1 | regulatory_records |
Source coverage
Source descriptions make coverage visible before a buyer logs into the portal or downloads the full snapshot.
Registry-reported study records from the U.S. National Library of Medicine ClinicalTrials.gov service.
Current DRKS records registered from 2025 onward or, for older registrations, last updated during 2025; the connector enforces that row-level licence gate and retains the public DRKS record link.
Public clinical-trial records from the European Union Clinical Trials Information System.
Public EudraCT study records from the European Union Clinical Trials Register.
Workflow coverage
These use cases are the workflows this dataset is positioned to support. The same workflow set appears on the homepage, sample page, and agent-facing docs.
Search across registries
Find studies by condition, intervention, sponsor, or registry identifier.
Build research datasets
Download study records with release dates, registry identifiers, and source links.
Link registry IDs
Review records linked across ClinicalTrials.gov, CTIS, EudraCT, ISRCTN, and the included DRKS subset.
Check registry coverage
Review included registries, available fields, and source refresh dates.
Limits
Coverage claims should stay bounded by the manifest caveats and source licence terms.
- TrialBase DB is reference data, not medical advice, trial recruitment advice or regulatory advice.
- Buyers remain responsible for validating suitability for regulated clinical, commercial or publication workflows.
- Array fields preserve registry-reported terms after trimming and exact-repeat deduplication; completeness and selected provenance are release-level measurements, not schema guarantees.
