Association between residential greenness and allergic diseases among adolescents in South Korea: A nationwide representative study.
Article in Pediatric allergy and immunology : official publication of the European Society of Pediatric Allergy and Immunology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundResidential greenness is an important environmental factor potentially influencing the development of allergic diseases in adolescents; however, its impact remains understudied in South Korea. This study aimed to examine the association between residential greenness and allergic disease prevalence using nationally representative data.
methodWe analyzed data from 1,130,598 adolescents (7-12th grade) participating in the Korean Youth Risk Behavior Web-based Survey (2007-2024). Residential greenness was estimated using the normalized difference vegetation index (NDVI) derived from satellite imagery based on GPS coordinates. Logistic regression models assessed associations between NDVI and physician-diagnosed allergic rhinitis (AR), atopic dermatitis (AD), and asthma, with subgroup analyses conducted by sex, school grade, household income level, and sufficiency of fatigue recovery.
resultsAmong 1,130,598 adolescents (51.27% boys), 525,979 (46.52%) participants reported allergic diseases: 363,167 (32.12%) with AR, 250,462 (22.15%) with AD, and 88,584 (7.84%) with asthma. Higher residential greenness was associated with lower adjusted odds ratios of AR (0.83 [95% CI, 0.78-0.89]), AD (0.75 [0.70-0.80]), and asthma (0.45 [0.41-0.50]), with the strongest inverse association observed for asthma. The protective association of greenness was stronger in middle school students compared to high school students and in the higher-income group compared to the low-income group.
conclusionResidential greenness was associated with a reduced prevalence of allergic diseases among Korean adolescents, with stronger protective associations observed among middle school students and those from higher-income households. These findings highlight the need to improve equitable access to green spaces for all adolescents.
