Circulating Omega-3 Fatty Acids and Cardiometabolic Outcomes: A Systematic Review of Publications From UK Biobank.
Synthesis in Lipids, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Studies have shown that omega-3 fatty acids may protect against cardiovascular diseases (CVDs) and related metabolic conditions. UK Biobank is a large cohort study that includes data on plasma omega-3 fatty acids at study entry and health outcomes during the follow-up period. The aim of this research is to explore the association between plasma omega-3 fatty acids (total omega-3 fatty acids, docosahexaenoic acid (DHA) and non-DHA omega-3 fatty acids) and cardiometabolic health outcomes by systematically reviewing publications from UK Biobank. Three databases (EMBASE, MEDLINE, CINAHL) were searched in September 2025 using key words. Based on inclusion/exclusion criteria, 16 publications were selected for inclusion (two cross-sectional and 14 longitudinal with a follow-up of 11 to 14 years). Sample size varied between 20,338 and 273,834 across the included studies. Eleven studies reported on CVD outcomes and five on metabolic outcomes. Plasma total omega-3 fatty acids and DHA were inversely associated with risk of coronary heart disease, CVD mortality, heart failure, haemorrhagic stroke and severe fatty liver disease. Plasma total omega-3 fatty acids were also inversely associated with risk of prediabetes and type-2 diabetes, while plasma DHA was also inversely associated with risk of coronary heart disease mortality, ischemic stroke and fatty liver disease. It is concluded that publications based on UK Biobank consistently demonstrate a significant association between higher levels of total omega-3 fatty acids or DHA in plasma and lower likelihood of poor cardiometabolic health outcomes, providing support for guidance for the population to achieve recommended intakes of these fatty acids.
