The uneven playing field: provider participation and regional disparities in oral health examination rates in Korea.

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
objectivesThis study investigated regional disparities in adult oral health examination rates in Korea, despite free oral health screenings by the National Health Insurance Service (NHIS). It focused on the impact of provider factors, such as the availability of dental clinics and non-dental institutions.
methodsA cross-sectional analysis of 2022 data from 229 districts was conducted. The dependent variable was the adult oral health examination rate, while independent variables included provider factors, community health status, lifestyle, demographic, and socioeconomic characteristics. Descriptive statistics, Pearson's correlation, and multiple regression analyses identified significant predictors.
resultsNon-metropolitan areas had higher oral health examination rates (27.4%) than metropolitan areas (25.3%). Correlation analysis showed the general health examination rate (r=0.583) and the number of screening institutions (r=0.234) were the strongest predictors (p<0.001). Regression analysis showed a 1% increase in general health examination rates led to a 1.44% rise in oral health examination rates (p<0.001).
conclusionsDespite NHIS policies, significant regional disparities persist, showing that providing screenings alone is insufficient. Integrating oral health screenings with general health examinations is necessary. Policymakers must promote collaboration between dental and non-dental providers to ensure equitable, integrated health services, enhancing preventive care and reducing disparities.
