Bibliographic record
Abstract
Hypertension and cognitive disorders are common problems in the elderly and their prevalence is increasing as the population ages. The present study aimed to investigate different aspects of cognitive function in elderly people with and without hypertension. It was a causal-comparative study. The statistical population included the elderly of Arak city, among them, two groups of 30 were selected through convenience sampling, one with hypertension based on medical records and the other non-hypertensive. Montreal test was used to assess cognitive performance dimensions. Results of multivariate analysis of variance showed that in all subscales of the Montreal test, the elderly without hypertension performed significantly better than the elderly with hypertension. The most significant differences between the two groups were known in the subscales of language, computation, and attention. This finding suggested the effects of high blood pressure on brain function. According to the results of this study, it is necessary to design and implement therapeutic protocols for the elderly with hypertension for their cognitive rehabilitation.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
