Junior physical mismatch
Age, height, weight, maturation and exposure — aggregated only. No named child records.
Schema ready. No public index is computed.
Player Welfare Observatory
Track the evidence. Distinguish signal from conclusion.
Rugby Sentinel’s player-welfare layer is information, not medical advice. Research findings may show association, not causation. Evidence changes. Individual risk cannot be derived from population-level data. No identifiable junior health records are published.
Concussion and head injury
Default unit is incidence per 1,000 player-hours. Raw counts without exposure are not shown as rates.
No verified exposure series is connected.
Return-to-play
Duration and compliance where a source exists. Not a clinical protocol.
Coverage unavailable.
Brain health evidence monitor
Dementia, CTE, MND/ALS, Parkinson’s, biomarkers, repetitive head impacts. Uncertainty is the point.
Monitor scaffolded. Studies added only after citation-level review.
