Healthy Food Corners as Spatial Nudges: Consumer Awareness, Perceived Necessity, and Design Preferences in Convenience Stores.
Article in Nutrients, 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/
objectivesHealthy Food Corners (HFCs) are zones in Korean convenience stores meant to promote healthier choices, yet how consumers respond to them remains unclear. Drawing on the Stimulus-Organism-Response (S-O-R) framework, this study examined consumer awareness and the perceived necessity of HFCs, identified preferences for their spatial and visual design, and exploratorily tested whether perceived necessity links awareness to healthy-food purchase intention.
methodsA cross-sectional online survey of 409 convenience store users aged 14-59 years in the Seoul metropolitan area was analyzed using hierarchical regression and bootstrapping mediation.
resultsA descriptive contrast was observed between awareness and perceived necessity: awareness of the HFC was low (three-item composite M = 2.90 ± 1.66), whereas perceived necessity was substantially higher (M = 4.86 ± 1.25), indicating that consumers valued the concept even with limited prior exposure. Consumers preferred HFCs in ready-to-eat refrigerator sections, with clear zoning labels, horizontal grouping, green color schemes, and eye-level placement, and these preferences differed by age. In an exploratory mediation analysis, awareness predicted perceived necessity, which in turn strongly predicted purchase intention; the indirect effect was significant (0.188, 95% CI [0.128, 0.251]) while the direct effect was non-significant, a pattern consistent with full mediation. Because perceived necessity was assessed with a single item, this pathway is interpreted cautiously. Purchase intention was self-reported rather than behaviorally assessed.
conclusionsOverall, the findings suggest that HFCs may function as distinct, strategically positioned spatial nudges; however, design recommendations are based on consumer-stated preferences and require confirmation through behavioral research. The results have implications for food environment policy in Korea, with the caveat that generalizability to other countries and retail systems warrants caution.
