Abstract

The health effects of omega-3 fatty acids have been controversial. Here we report the results of a de novo pooled analysis conducted with data from 17 prospective cohort studies examining the associations between blood omega-3 fatty acid levels and risk for all-cause mortality. Over a median of 16 years of follow-up, 15,720 deaths occurred among 42,466 individuals. We found that, after multivariable adjustment for relevant risk factors, risk for death from all causes was significantly lower (by 15–18%, at least p < 0.003) in the highest vs the lowest quintile for circulating long chain (20–22 carbon) omega-3 fatty acids (eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids). Similar relationships were seen for death from cardiovascular disease, cancer and other causes. No associations were seen with the 18-carbon omega-3, alpha-linolenic acid. These findings suggest that higher circulating levels of marine n-3 PUFA are associated with a lower risk of premature death.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Observational studies consistently show that an O3I of ≥8% is ideal for reducing risk of major adverse cardiovascular events, stroke, and all-cause mortality.

    “Observational studies consistently show that an O3I of ≥8% is ideal for reducing risk of major adverse cardiovascular events116 (MACE), stroke20 and all-cause mortality117.”

    From Effects of Omega-3 Fatty Acid Treatment on Risk for Atrial Fibrillation: An Updated Meta-Analysis of 35 Trials including 114 592 Individuals (2026) · cites this paper as [117]

    Citation 117 is attached to the all-cause mortality portion of the sentence. The Results (Total mortality; page not supplied) associate higher EPA + DHA levels with lower all-cause mortality, but the Methods (Statistical analysis and pooling; page not supplied) say the analysis used cohort-specific quintiles rather than an absolute percentage. The paper therefore does not establish an O3I of ≥8% as an ideal threshold or show that reaching it reduces mortality. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
