Association between the dietary omega-6 to omega-3 fatty acid ratio and age-related macular degeneration in Korean adults.
Article in Nutrition journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
backgroundLong-chain polyunsaturated fatty acids of the omega-6 and omega-3 families affect processes implicated in vascular and neural retinal disease pathogenesis. This study aimed to investigate the association between the dietary omega-6 to omega-3 fatty acid ratio and age-related macular degeneration (AMD).
methodsWe conducted a cross-sectional analysis using a nationwide representative sample of older adults (≥ 50 years), including 1,944 men and 2,592 women, from the Korea National Health and Nutrition Examination Survey (2017-2018). Omega-6 and omega-3 fatty acid intakes were collected through a 24-hour recall method and used to calculate the omega-6 to omega-3 fatty acid ratio. Associations between the ratio and AMD were determined using odds ratios (ORs) from multivariate logistic regressions.
resultsThe prevalence of AMD was 19.8% and 17.7% in Korean men and women, respectively. In women, the multivariable-adjusted OR for incurring AMD was significantly higher in the 2nd (OR = 1.36; 95% CI = 1.02-1.81) and 3rd (OR = 1.36; 95% CI = 1.02-1.83) tertiles of the dietary omega-6 to omega-3 fatty acid ratio than in the 1st tertile (OR = 1, the reference OR) (P = 0.036 for this trend). However, this association was not observed in men.
conclusionsThese results suggest that high omega-6 to omega-3 fatty acid ratios may be associated with an increased prevalence of AMD among Korean women.
