CORRELATED CHANGES IN GRIP STRENGTH AND COGNITION: MULTI-STUDY RESULTS BASED ON BIVARIATE LINEAR GROWTH MODELING
Bibliographic record
Abstract
We investigated the association between rates of change in grip strength and indicators of different domains of cognitive function (mental status, processing speed, attention and working memory, perceptual reasoning, verbal ability, and learning and memory) within a multiple-study comparative framework. Bivariate growth models stratified by gender were conducted across nine studies affiliated with the Integrative Analysis of Longitudinal Studies of Aging and Dementia research network. We summarized results using meta-analysis. We found consistent moderate-to-strong associations between grip strength and each cognitive domain for both males and females. Meta-analysis showed an overall average correlation coefficient of 0.55 (95%CI = 0.44 – 0.56), and a range spanning from -0.49 for Learning and Memory in males to 0.92 for Processing Speed in males. Our coordinated meta-analysis provided evidence for a consistent association between changes in grip strength and changes across a broad range of cognitive functioning.

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.
