Food literacy as a moderator in the relationship between food security and dietary diversity among adults in Seoul: based on the 2021-2023 Seoul Food Survey.
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/
objectivesFood literacy (FL) and food security are key factors influencing healthy eating and dietary diversity. This study examined whether FL moderates the relationship between food security and dietary diversity score (DDS) among adults in Seoul. SUBJECTS/
methodsData were obtained from the 2021-2023 Seoul Food Survey and included 8,248 adults aged 18-64 yrs. The DDS was calculated based on daily intake from 5 food groups (0-5 points). Food security was classified as secure or insecure. FL was assessed using a 33-item scale across nutritional and safety, cultural and relational, and socioecological domains. Participants were grouped into three FL levels. χ
resultsFood-secure participants had significantly higher DDS (2.47 vs. 2.22,
conclusionFL moderates the relationship between food security and dietary diversity, with this association varying across FL levels. FL education may improve diet quality, particularly in food-insecure populations.
