Association Between the Korean Healthy Eating Index and Hyperuricemia Among Korean Adults.
Article in Journal of Korean medical science, 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
backgroundHyperuricemia is an emerging public health concern associated with gout and metabolic diseases. While numerous studies have examined associations between individual dietary factors and hyperuricemia, comprehensive assessments of overall diet quality and their impact on hyperuricemia are lacking. This study aimed to investigate the association between overall diet quality, as measured by the Korean Healthy Eating Index (KHEI), and the prevalence of hyperuricemia among Korean adults using nationally representative data.
methodsWe analyzed data from 27,149 Korean adults aged ≥ 20 years from the Korea National Health and Nutrition Examination Survey (2016-2021). The KHEI assesses dietary quality based on adherence to Korean dietary guidelines, encompassing adequacy, moderation, and balance of intake. Hyperuricemia was defined as serum uric acid ≥ 7.0 mg/dL in men and ≥ 6.0 mg/dL in women. Logistic regression was performed, adjusting for sociodemographic, lifestyle, and health-related factors.
resultsHigher total KHEI scores were significantly associated with a lower prevalence of hyperuricemia (10.6% vs. 15.5%;
conclusionOur findings demonstrate a significant inverse relationship between overall dietary quality, assessed using the KHEI, and hyperuricemia risk among Korean adults. The results emphasize the protective effects of balanced dietary habits, highlighting the benefits of regular breakfast consumption, increased fruit and vegetable intake, and balanced energy distribution. These insights underscore the importance of adopting holistic dietary strategies for the prevention and management of hyperuricemia, moving beyond traditional recommendations focused on individual nutrients. Further longitudinal studies are required to clarify causality and mechanisms underlying these associations.
