Associations of mediterranean diet score and age-related macular degeneration in Korean elderly.
Article in BMC public health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundPrevious studies have reported associations between individual nutrients or specific foods and the risk of age-related macular degeneration (AMD). However, the relationship between overall dietary quality, specifically the alternative Mediterranean diet (aMED) score, and AMD remains unclear. Therefore, this study aimed to investigate the association between the aMED score, as an indicator of overall diet quality, and AMD in the Korean population.
methodsWe conducted a cross-sectional analysis using nationally representative samples of older adults aged ≥ 65 years (895 men and 1,191 women) from the Korea National Health and Nutrition Examination Survey (2017-2018). Food intake and the aMED score were estimated using 24-h recall. AMD was diagnosed by an ophthalmologist based on fundus photography. The associations of aMED score tertiles with AMD were determined using odds ratios (ORs) from multivariate logistic regressions.
resultsMultiple logistic regression analysis revealed a significantly negative association between the aMED score and AMD (adjusted ORs = 0.58; 95% confidence interval = 0.39-0.88; p-trend = 0.021) in older men after adjusting for confounding factors such as age, body mass index, family monthly income, current smoking, alcohol consumption, physical activity, chronic disease status, and energy intake. Notably, this association was exclusively observed in men, and no significant association was observed between the aMED score and AMD in women (adjusted OR = 0.88; 95% CI = 0.61-1.29; p-trend = 0.691).
conclusionsThis study's findings suggest that a high aMED score may be associated with a reduced risk of AMD in older men. Future studies with larger sample sizes and a prospective or interventional design are required to enhance current understanding regarding the association between diet quality and AMD.
