Abstract
BACKGROUND: Omega-3 fatty acid (OM3) intake is associated with a lower risk of developing Alzheimer’s disease, but individuals carrying the ɛ4 allele of apolipoprotein E (APOE4) might not benefit from this prevention strategy. Indeed, they might have lower OM3 into plasma free fatty acid (FFA) and lysophosphatidylcholine (LPC) compartments, the two forms the brain can take-in. OBJECTIVE: To evaluate the docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) concentrations in the FFA and LPC pre- and post-OM3 supplementation in APOE4 carriers and non-carriers. DESIGN: Plasma samples from 25 APOE4 carriers and non-carriers before and six months after receiving 2.5 g/d DHA+EPA daily were analyzed. DHA and EPA concentrations in the LPC, and FFA were compared by supplementation and genotype. A secondary analysis investigated the interaction between body mass index (BMI) and APOE genotype status. RESULTS: There was no genotype x supplement interaction nor a genotype effect on LPC and FFA. However, there was a supplement effect where OM3 increased in all lipid compartment by < 1-fold to 4-fold. Individuals with a low BMI had higher OM3 increase concentrations in the LPC than those with a high BMI. CONCLUSIONS: APOE4 carriers and non-carriers can both benefit from taking an OM3 supplement. However, individuals with a high BMI have lower OM3 increases than those with a lower BMI.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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
