Research Gap Index

Burden percentile minus research-activity percentile (publications, last 5 years) within the same scope. Positive values flag cancers with high mortality burden but comparatively little literature. Caveat (Phase 1): literature counts are query-based per entity (query stored on each row); they are not aggregated over descendants.
