Physical Fitness is a Mediator in the Relationship between Arterial Stiffness and Cognitive Function
Bibliographic record
Abstract
Abstract Background To investigate physical fitness as a mediator of the relationship between arterial stiffness and cognitive function in seniors. Methods This is a cross-sectional study comprising 155 individuals free from chronic diseases (75.5 ± 6.5 years; 69.7% female). Carotid-femoral pulse wave was assessed through applanation tonometry. Cognitive function was evaluated with Montreal Cognitive Assessment (MoCA). Physical fitness was assessed through handgrip strength and Senior Fitness Test (SFT). A Z -score including individual physical fitness components was computed as a global index of physical fitness. Hayes’s PROCESS macro for Statistical Package for the Social Sciences was used for the simple mediation analysis, using bootstrapped procedures. Results After adjustments for sex and age, physical fitness Z -score mediated the relationship between arterial stiffness and cognitive function [Indirect effect = −0.382 (95% CI −0.670 to −0.138)]. Conclusion Findings suggest that physical fitness, independently of sex and age, is a mediator on the relationship between arterial stiffness and cognitive function in seniors free from chronic diseases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
