Association of language markers with future cognitive impairment and presence of limbic predominant age related TDP‐43 encephalopathy is a dataset published in Alzheimer s & Dementia (2025). On theSindex it has a DataRank of 0, placing it in the top 100% of the data-sharing corpus. Its calibrated FAIR score is 8/100.
Ranks in the top 100% for downstream scientific impact
DataRank reads this dataset's downstream impact straight off the citation graph — no black box, no proprietary weighting. How is this computed?
FAIR checklist signals are shown for context only and do not affect DataRank scoring.
Full FAIR picture · advisory
The headline score is computed from the scored criteria — the fact-shaped checks (a repository, an accession, a licence) that two independent models agree on. The advisory criteria below are real FAIR guidance but rest on judgment calls that models read differently, so they inform without moving the number.
No persistent identifier string (DOI, Handle, ARK, repository accession) is provided for the dataset; the paper's own DOI is for the article, not the data.
