Abstract

fetched live from OpenAlex

According to Statistics Canada in 2014, 23.4% of Canadians aged between 45 and 64-years-old, and 47, 4% of adults aged 65 years and older were diagnosed with hypertension. Given the significant association between Hypertension and cognitive decline, and consequently on frailty status, the contribution of Neurocognitive Frailty Index in the assessment of patient's prognosis is of utmost importance. Hence, the prognostic utility of the Neurocognitive Frailty Index (NFI), a comprehensive measure of frailty in the elderly and a correlated measure of cognitive change, could help shed some light in better understanding of this relationship.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
