Lipid-Lowering Agents and the Risk of Cognitive Impairment That Does Not Meet Criteria for Dementia, in Relation to Apolipoprotein E Status
Bibliographic record
Abstract
Lipid-lowering agents (LLAs) might lower the risk of dementia, but any impact on other forms of cognitive impairment is not clear. We examined LLAs in relation to cognitive impairment, no dementia (CIND) and apolipoprotein E4 status. In a case control study from the Canadian Study of Health and Aging, cases (n = 347) had developed CIND between the first and second study waves and controls (n = 693) had no cognitive impairment at either time. LLA use was associated with a lower odds of incident CIND in those <80 years of age (OR 0.37; 95% CI 0.15-0.93) but not for those aged >or=80 years (OR 0.56; 95% CI 0.15-2.10). The reduced risk was significant for statins but not for other LLAs. Adjusting for apolipoprotein E4 status did not change the point estimates of the ORs. The greatest impact of LLAs was seen in the CIND subtype circumscribed memory impairment.

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.
