Impact of a Community-Based Preventive Oral Health Program on Oral Health-Related Quality of Life in School-Aged Children.
Observational study in International journal of paediatric dentistry, 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
backgroundAlthough community-based programs are implemented to promote children's oral health, evidence regarding their impact on oral health-related quality of life (OHRQoL) remains limited.
aimTo evaluate changes in OHRQoL among schoolchildren following participation in a community-based oral health program and to identify factors associated with post-intervention OHRQoL.
designThis observational pre-post study included 668 schoolchildren in Seoul, South Korea, participating in the Student Dental Home Program. OHRQoL was assessed before and after the program using the Korean COHIP-SF 19. Changes in scores were analyzed using paired t-tests, and factors associated with post-intervention OHRQoL were examined using ANCOVA and linear regression analyses.
resultsTotal scores increased significantly (mean difference 3.7, 95% CI 3.3-4.1; Cohen's d = 0.66). Significant increases were observed across all subscales, with the largest effect in the Oral Health subscale (d = 0.81). In the simple regression analyses, spontaneous tooth pain, gingival bleeding, halitosis, and malocclusion were associated with lower scores. In the multivariable model, malocclusion remained the only factor independently associated with lower scores (B -0.66, 95% CI-1.37 to -0.01, p = 0.048).
conclusionsOHRQoL scores increased following participation in a community-based oral health program. Malocclusion remained independently associated with lower post-intervention OHRQoL after baseline adjustment.
