Evidence Explorer¶
Status: PUBLIC_ALPHA · included in v0.1.0
Evidence Explorer is a read-only research surface that shows why NosoGraph holds a claim — from the claim itself through supporting, contradictory, and inconclusive evidence, provenance, and original source metadata.
What is a claim?¶
A claim is a structured biomedical statement in the knowledge graph, such as:
- a condition associated with a gene or phenotype
- a treatment indicated for a condition
- a mechanism linked to a pathway
Claims are associations, not proof of causation. The exact relationship type appears on each claim row.
How do I open Evidence Explorer?¶
- Open the NosoGraph dashboard (
/). - Click Evidence in the top navigation, or Evidence Explorer in the hero quick actions.
- Or open a condition in Conditions, pick a claim, and click Open in Evidence Explorer.
Deep link: ?claim_id={uuid}#evidence-explorer — shareable URLs reload the same claim.
Evidence directions¶
| Label | Meaning |
|---|---|
| SUPPORTS | Evidence in the dataset supports the claim |
| CONTRADICTS | Evidence disagrees with the claim |
| INCONCLUSIVE | Mixed or insufficient evidence in the dataset |
| UNASSERTED | No directional evidence recorded |
Supporting evidence does not mean contradictory evidence is absent — check each group separately.
Evidence quality badges¶
Quality dimensions describe context, not a single confidence score. Missing metadata shows as unknown — absence is not treated as low quality.
| Dimension | Examples |
|---|---|
| Species | human, animal, in vitro, computational, unknown |
| Study design | RCT, cohort, review, unknown |
| Origin | curated, imported, generated, unknown |
| Human review | none, community, expert, unknown |
UNKNOWN means the field was not recorded or could not be derived conservatively from stored metadata.
Provenance¶
The provenance timeline shows how data reached the graph:
source snapshot → normalized record → ingestion → graph claim
Incomplete chains are shown honestly — NosoGraph does not invent missing stages.
Original sources¶
Each evidence row links to source metadata (PubMed ID, trial registry, ontology record, etc.). Use View source when a URL or external identifier is available.
Filters¶
Filter evidence by direction, species context, and sort order. Filter state is reflected in the URL so refresh and back/forward navigation preserve your view.
API export¶
Use the JSON/API link on a loaded claim to open the underlying /api/v1/claims/{id} response, or call the API directly. The evidence list is paginated:
GET /api/v1/claims/{claim_id}/evidence?limit=50&offset=0
Research disclaimer¶
NosoGraph is for research use only. Associations are not causation. Not medical advice.
