Social capital and regional influences: key predictors of unmet dental care needs among older adults in Korea.
Article in Epidemiology and health, 2025. 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
objectivesAccess to dental services is essential for improving quality of life, and social capital plays a key role in facilitating that access. This study aimed to identify individual-level and regional-level factors, including social capital, that predict unmet dental care needs among older adults.
methodsWe analyzed data from 59,414 older adults obtained from the 2023 Korea Community Health Survey and the Korean Statistical Information Service, employing a 2-level multilevel model. The dependent variables comprised 3 types of unmet dental care needs: overall, due to lack of acceptability, and due to economic reasons. Twelve independent variables, including social capital and other individual and regional factors, were examined.
resultsThe prevalence of unmet needs was 14.15% overall, 8.70% for acceptability reasons, and 4.85% for economic reasons. Lower individual social capital was associated with higher odds of unmet dental care needs, whereas regional social capital factors demonstrated no significant association. Residing in regions with higher fiscal independence ratios was related to an increased likelihood of economic unmet needs (odds ratio [OR], 1.29; 95% confidence interval [CI], 1.09 to 1.52). In contrast, a greater density of dentists per 10,000 population was inversely associated with overall and acceptability-related unmet needs (OR, 0.82 for both; 95% CI, 0.73 to 0.92 and 0.73 to 0.93, respectively).
conclusionsIndividual social capital and specific regional factors-namely, fiscal independence and density of dentists-may represent important determinants of unmet dental care needs among older adults. Policy interventions aimed at reducing unmet needs should consider these variables.
