# Focused literature verification — 1 November 2026

Purpose: verify primary sources needed to explain source compatibility, outcomes and burden for this three-study atlas. This was a targeted narrative exercise, not a registered or exhaustive systematic review. No PRISMA counts or formal risk-of-bias assessment are claimed.

Starting materials: the three local README files, literature discussions, data dictionaries and handoff limitations. Followed their dataset DOIs and original papers; checked primary publisher, PubMed/PMC and institutional records for exact titles, authors and scope. Search concepts included the exact RIC descriptor title, Lövdal competitive-runner injury prediction and erratum, IOC 2020 injury/illness surveillance and injury burden.

Verified sources are listed in `config/references.json`. Primary records include:

- RIC descriptor: https://pmc.ncbi.nlm.nih.gov/articles/PMC11564798/ — verified exact title, study scope and data citation to Figshare v1. A newer indexed version was not substituted for the source version used locally.
- Competitive Runners original article: https://pubmed.ncbi.nlm.nih.gov/33931574/ — verified authors, title and population. Dataset DOI and authors were also checked through the University of Groningen institutional record because Dataverse presented an automated-access barrier: https://research.rug.nl/nl/datasets/replication-data-for-injury-prediction-in-competitive-runners-wit/ . The exact corrected lag suffix order remains grounded in the pinned source project and its corrected source README, not inferred from a bibliographic abstract.
- IOC consensus: https://pmc.ncbi.nlm.nih.gov/articles/PMC7146946/ — definitions, exposure and reporting distinctions.
- Burden editorial: https://pubmed.ncbi.nlm.nih.gov/29021247/ — frequency and consequences as distinct dimensions.

The football source version and licensing are preserved from the audited project manifest. No independent upstream clinical verification was added. Numerical results in the atlas come from the frozen project outputs, not from article abstracts. No article full text or third-party figure is redistributed.
