Associations between dietary factors and serum uric acid levels in Korean women aged 19-65 years.
Article in Nutrition research and practice, 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
BACKGROUND/
objectivesHyperuricemia is associated with an increased risk of chronic diseases such as hypertension, type 2 diabetes mellitus, and chronic kidney disease. This study investigated the dietary factors associated with the serum uric acid (SUA) levels in Korean women. SUBJECTS/
methodsThis study analyzed the data from the 2016-2017 Korea National Health and Nutrition Examination Survey, including 4,201 women aged 19-64 yrs. The dietary intake was assessed using a single 24-h dietary recall, and the SUA levels were categorized into quartiles. Multivariate linear regression analyses were conducted to examine the associations between the nutrient and food group intake and the SUA levels after adjusting for potential confounders.
resultsHigher intakes of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) were significantly associated with elevated SUA levels, whereas carbohydrate intake had a significant inverse association with the SUA levels. Dietary fiber intake was lower in the highest SUA quartile than in the lowest quartile, but dietary fiber was not independently associated with the SUA levels after a full adjustment. At the food group level, higher intakes of meat and high-purine seafood were positively associated with the SUA levels, whereas the grain intake showed an inverse association.
conclusionHigher SUA levels may be associated with dietary patterns characterized by an increased intake of fats, particularly SFA and MUFA derived from animal-based foods, rather than the isolated effects of individual fatty acids. Carbohydrate- and grain-based dietary components may play a protective role in uric acid metabolism. Considering the link between elevated SUA and the chronic disease risk, dietary management focusing on overall dietary patterns rather than single nutrients may be an important preventive approach. Further prospective cohort studies will be needed to confirm the causal relationships between diet and the SUA levels in the general Korean population.
