Effects of ethyl-eicosapentaenoic acid omega-3 fatty acid supplementation on hot flashes and quality of life among middle-aged women
Bibliographic record
Abstract
OBJECTIVE: To compare the effects of enriched ethyl-eicosapentaenoic acid (E-EPA) omega-3 fatty acid supplementation with those of placebo on hot flashes (HFs) and quality of life among middle-aged women. METHODS: Women were considered for participation if they were between 40 and 55 years of age and had moderate to severe psychological distress. A total of 120 women were randomly assigned to E-EPA or placebo for 8 weeks. Only women with HFs were included in this analysis (E-EPA, n = 45; placebo, n = 46). Outcomes were changes from baseline to week 8 postintervention regarding hot flash (HF) frequency (number of HFs per day), intensity and score (frequency x intensity), and Menopause-specific Quality of Life questionnaire scores. RESULTS: At baseline, the average number of HFs was 2.8 per day. After 8 weeks, HF frequency and score decreased significantly in the E-EPA group compared with the placebo group. There was no difference in the change in HF intensity between groups. Frequency of HFs declined by a mean of 1.58 per day (95% CI, -2.18 to -0.98) in the E-EPA group and by 0.50 per day (95% CI, -1.20 to 0.20) in the placebo group. The odds of being a responder among those taking E-EPA were about three times greater than among those taking placebo (odds ratio, 2.70; 95% CI, 1.03-7.03; P = 0.04). Menopause-Specific Quality of Life scores improved significantly over time in both groups but no significant differences were noted between them. CONCLUSIONS: Supplementation with E-EPA omega-3 fatty acid reduced HF frequency and improved the HF score relative to placebo. These results need to be confirmed by a clinical trial specifically designed to evaluate HFs in more symptomatic women.

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.
