Chronic disease and smoking cessation intention: associations with oral health status, behaviors, and care in Korea.
Article in Frontiers in public health, 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: Oral conditions are immediately perceptible in daily life and may act as proximal factors associated with smokers' intention to quit, yet it is unclear whether these associations differ by chronic disease status. Methods: We analyzed nationally representative Korea Community Health Survey data (2010-2024) for current smokers aged ≥30 years ( Results: Approximately 27% had chronic diseases; the survey-weighted prevalence of cessation intention was 62.6 vs. 66.0% in chronic-disease and non-chronic groups, respectively. After full adjustment, chronic disease was associated with higher odds of intention (OR = 1.19; 95% CI: 1.11-1.26). Oral status and oral-hygiene behaviors were positively associated with intention. Dental scaling remained positively associated (OR = 1.11; 95% CI: 1.04-1.17), whereas routine checkups were borderline/non-significant (OR = 1.06; 95% CI: 1.00-1.12). Reporting unmet dental care was also associated with higher intention (OR = 1.21; 95% CI: 1.14-1.29). No statistically significant heterogeneity across chronic-disease strata was observed; formal interaction tests were not significant after Holm-Bonferroni adjustment, and marginal predicted probabilities showed only small absolute differences. Conclusion: In this nationally representative sample, oral health status, hygiene behaviors, and dental care utilization showed modest yet consistent associations with smokers' intention to quit, without meaningful modification by chronic disease status. These findings support embedding evidence-based cessation support within routine dental and chronic-disease care and using observable oral health cues as conversation starters to motivate quitting.
