Edges
Every edge, grouped by relationship
Source-native edges first (aggregated per neighbour, direction, evidence level and source), then derived registry links. Up to 15 per relationship (10 trials); “show all” raises one group to 200.

An edge is a relationship stated by a source (CIViC evidence item, ChEMBL indication or mechanism, openFDA approval) and kept with its native evidence level, direction and cancer context — CancerIndex never infers, merges or re-scales it. Rows marked derived are counts and measurements read from registries (ClinicalTrials.gov conditions and interventions, GDC/cBioPortal cohort frequencies ≥ 5 % with ≥ 20 cases affected, regulatory approval records): they say how often two entities co-occur in a registry, not that a source asserted a biological or clinical link. Trials are rolled up over the cancer and its descendants; approvals list authority, jurisdiction and date as published.
