1 · What the graph read from it

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.

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.

Abstract

backgroundAnimal models support dietary omega-3 fatty acids protection against abdominal aortic aneurysm (AAA), but clinical data are scarce. The sum of red blood cell proportions of the omega-3 eicosapentaenoic and docosahexaenoic acids, known as omega-3 index, is a valid surrogate for long-term omega-3 intake. We investigated the association between the omega-3 index and the prevalence and progression of AAA. We also investigated associations between AAA and arachidonic acid, an omega-6 fatty acid that is a substrate for proinflammatory lipid mediators. METHODS AND

resultsWe obtained blood samples from 498 AAA patients (maximal aortic diameter ≥30 mm) within a population-based ultrasound-screening trial in men and from 199 age-matched controls who screened negative. We determined the fatty acids of red blood cells by gas chromatography. During a median follow-up of 4.85 years, 141 AAA patients reached criteria for vascular surgical repair. Participants were high consumers of omega-3 (average omega-3 index: 7.6%). No significant associations were found for omega-3 index. In contrast, arachidonic acid in AAA patients was higher than in controls (

conclusionsOmega-3 index is unrelated to men with AAA from a country in which fish consumption is customarily high. Arachidonic acid is associated with AAA presence and progression. CLINICAL
