Association between the Korean Healthy Eating Index sub-domains and the risk of metabolic syndrome in Korean adults: data from the 2022-2023 Korea National Health and Nutrition Examination Survey.

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/
objectivesTo evaluate the association between the Korean Healthy Eating Index (KHEI) scores and metabolic syndrome (MetS) and its risk factors in Korean adults, focusing on 3 KHEI domains. SUBJECTS/
methodsData from 9,161 adults (3,985 men, 5,176 women) aged 19-64 yrs who participated in the 2022-2023 Korea National Health and Nutrition Examination Survey were analyzed. MetS was diagnosed using the National Cholesterol Education Program-Adult Treatment Panel III criteria. The KHEI scores were calculated using the revised 2022 KHEI. Statistical analysis was performed using complex sample design methods, including the Rao-Scott χ
resultsThe risk of MetS was significantly lower in the group with highest total KHEI score than in the group with lowest score in men (odds ratio, 0.658; 95% confidence interval [CI], 0.492-0.881). Among the 3 domains, Adequacy was the most effective predictor of MetS. The highest score group exhibited significantly decreased odds of MetS in men (0.689; 95% CI, 10.523-0.909) and women (0.665; 95% CI, 0.456-0.969). Total KHEI scores were significantly lower in the MetS group than in the non-MetS, in both men and women (
conclusionThese findings reveal that a high quality diet, particularly in the Adequacy domain, is associated with a lower risk of MetS. Dietary patterns within each KHEI domain may differentially influence MetS risk. Therefore, future nutritional strategies for the prevention of MetS should focus on improving the adequacy of essential food groups.
