Residential Greenness and Risk of Coronary Artery Disease Following COVID-19: A Nationwide Cohort Study in South Korea.
Article in Journal of the American Heart Association, 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
backgroundResidential greenness has been associated with lower ischemic heart disease risk in general populations; however, its relevance after SARS-CoV-2 infection is unclear. We evaluated the associations between residential greenness and incident coronary artery disease following COVID-19.
methodsIn this nationwide cohort study using the South Korean K-COV-N (Korea Disease Control and Prevention Agency-COVID-19-National Health Insurance Service) database, we included individuals aged
resultsAmong 3 097 179 individuals (61.4% men), 25.3%, 59.7%, and 15.0% were classified as having low, moderate, and high NDVI exposure, respectively. Although NDVI was not associated with risk of acute coronary syndrome, higher NDVI was associated with lower risk of chronic ischemic heart disease (aHR, 0.86 [95% CI, 0.84-0.88] for moderate NDVI; aHR, 0.82 [95% CI, 0.80-0.84] for high NDVI). Associations were stronger in moderate to severe COVID-19, vaccinated individuals, males, and younger individuals.
conclusionsResidential greenness was not associated with post-COVID acute coronary events but was consistently associated with lower chronic ischemic heart disease risk, suggesting a potential role in long-term cardiovascular health after SARS-CoV-2 infection.
