Abstract
BACKGROUND/OBJECTIVE: We examine whether midlife vascular risk factors (VRFs) are associated with increased risk of incident Alzheimer's disease (AD) in a systematic review and meta-analysis of published cohort studies. METHODS: Original cohort studies were included if they reported adjusted combined odds ratio (COR) and corresponding 95% confidence intervals (CIs) or enough information to quantify the association between risk for AD in late-life and baseline VRFs of midlife. RESULTS: There were positive and significant associations between high blood pressure (COR 1.31; 95% CI: 1.01-1.70), hypercholesterolemia (COR 1.72; 95% CI: 1.32-2.24), obesity (COR 1.88; 95% CI: 1.32-2.69), and diabetes mellitus in midlife (COR 1.4; 95% CI: 1.25-1.57). Smoking and hyperhomocysteinemia (although only one high-quality paper) were also associated with an increased risk of AD generally. CONCLUSIONS: These results strengthen the epidemiological evidence that VRFs of midlife significantly increase risk for AD.

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 it
