Effect of Regional Deprivation and Dental Care Resources on the Unmet Dental Care Needs due to Cost of Older Individuals in South Korea.
Article in Gerodontology, 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
objectivesTo provide policy-relevant evidence to reduce oral health disparities and improve dental care accessibility by considering characteristics of urban and rural areas.
backgroundIndividual and regional factors influence dental care access. Regional poverty and limited dental resources among older adults may contribute to unmet dental care needs due to cost. MATERIALS AND
methodsA multilevel logistic regression analysis was conducted to examine the association between regional factors (regional deprivation, number of dentists per 10,000 and number of dental offices per 100,000) and unmet dental care needs due to cost. The analysis was adjusted for individual factors, such as sex, education, marital status, household income, subjective health status, chewing difficulty and limited daily activities, as determined by the 2021 Korean Community Health Survey (KCHS; n = 47,802).
resultsThe prevalence of unmet dental care needs due to cost was 4.94% in urban and 4.80% in rural older adults. Individuals who lived in higher regional deprivation (poorer regions) were less likely to experience unmet dental care needs due to cost (OR = 0.66, 95% CI = 0.47-0.94) only in rural areas. Individuals residing in areas with a higher number of dentists per 10,000 were more likely to experience unmet dental care needs due to cost in urban (OR = 2.19, 95% CI = 1.01-4.73) and rural (OR = 1.97; 95% CI = 1.16-3.34). Household income and oral health status were the strongest predictors of unmet dental care needs due to cost.
conclusionsThe influence of regional poverty, dentist distribution and individual factors should be considered in developing policies to reduce the unmet dental care needs of older Koreans.
