Abstract

BACKGROUND: The use of n-3 fatty acids may prevent cardiovascular events in patients with recent myocardial infarction or heart failure. Their effects in patients with (or at risk for) type 2 diabetes mellitus are unknown. METHODS: In this double-blind study with a 2-by-2 factorial design, we randomly assigned 12,536 patients who were at high risk for cardiovascular events and had impaired fasting glucose, impaired glucose tolerance, or diabetes to receive a 1-g capsule containing at least 900 mg (90% or more) of ethyl esters of n-3 fatty acids or placebo daily and to receive either insulin glargine or standard care. The primary outcome was death from cardiovascular causes. The results of the comparison between n-3 fatty acids and placebo are reported here. RESULTS: During a median follow up of 6.2 years, the incidence of the primary outcome was not significantly decreased among patients receiving n-3 fatty acids, as compared with those receiving placebo (574 patients [9.1%] vs. 581 patients [9.3%]; hazard ratio, 0.98; 95% confidence interval [CI], 0.87 to 1.10; P=0.72). The use of n-3 fatty acids also had no significant effect on the rates of major vascular events (1034 patients [16.5%] vs. 1017 patients [16.3%]; hazard ratio, 1.01; 95% CI, 0.93 to 1.10; P=0.81), death from any cause (951 [15.1%] vs. 964 [15.4%]; hazard ratio, 0.98; 95% CI, 0.89 to 1.07; P=0.63), or death from arrhythmia (288 [4.6%] vs. 259 [4.1%]; hazard ratio, 1.10; 95% CI, 0.93 to 1.30; P=0.26). Triglyceride levels were reduced by 14.5 mg per deciliter (0.16 mmol per liter) more among patients receiving n-3 fatty acids than among those receiving placebo (P<0.001), without a significant effect on other lipids. Adverse effects were similar in the two groups. CONCLUSIONS: Daily supplementation with 1 g of n-3 fatty acids did not reduce the rate of cardiovascular events in patients at high risk for cardiovascular events.

  • Even among omega-3 fatty acid studies, there are marked differences with respect to the relatively low doses of omega-3 administered and the ratio of EPA to DHA.

    “Even among omega‐3 fatty acid studies, there are marked differences with respect to the relatively low doses of omega‐3 administered and the ratio of EPA to DHA.16, 17, 18, 19, 20, 21, 22, 23, 24”

    The Randomization, Study Intervention, and Follow-up section specifies this trial’s 1-g dose and its EPA and DHA amounts. The Discussion says doses tested across trials ranged from 0.4 g to 4.8 g, supporting variation in dose, but our copy does not establish that EPA-to-DHA ratios differed across studies. (LLM, conf=0.83)

  • In the ORIGIN trial, administration of 1 g/day of combined EPA + DHA (465 mg EPA and 375 mg DHA) had no impact on cardiovascular mortality in more than 12,000 patients with impaired fasting glucose and at high risk for cardiovascular events.

    “In the ORIGIN trial, which enrolled more than 12,000 patients with impaired fasting glucose and at high risk for cardiovascular events, the administration of 1 g/day of combined EPA + DHA (465 mg of EPA and 375 mg of DHA) had no impact on cardiovascular mortality [89].”

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.
