Education moderates the association between self-rated oral health and oral health-related quality of life.

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
objectiveThe concept of oral health-related quality of life (OHRQoL) has gained significant attention, and self-rated oral health (SROH)-a brief measure to evaluate oral health-has been reported to correlate with OHRQoL. The relationship between education and OHRQoL has shown divergent findings. This study aims to investigate the relationship among education, SROH and OHRQoL.
methodsThis study involved 1917 participants and their demographic information, SROH and OHRQoL were collected. We used Oral Health Impact Profile-5(OHIP-5) to evaluate OHRQoL. Correlations between variables and moderating effect were conducted through statistical analysis.
resultsA poorer SROH was significantly correlated with higher OHIP-5 scores (r = 0.41, p < 0.001). Although highly educated individuals exhibited higher OHIP-5 scores, the association was weak (r = 0.11, p < 0.001). After adjusting for confounders, OHIP-5 remained associated with SROH (p ≤ 0.035) and education (p ≤ 0.008).The orthogonal polynomial regression test showed that Education-Linear (β = 1.477, p < 0.001), SROH-Linear (β = 4.572, p < 0.001) and SROH-Quadratic (β = 1.155, p < 0.001) were significant. The interaction test between SROH-Linear and Education-Linear(β = 1.213, p = 0.035) was significant demonstrating the moderating effect of education between SROH and OHIP-5.
conclusionSROH correlated with OHRQoL while education exhibited statistically significant but clinically negligible correlation with OHRQoL. Education moderated the relationship between SROH and OHRQoL. CLINICAL RELEVANCE: Education's moderating role suggests high-educated individuals may exhibit greater sensitivity and elevated expectations to oral health, intensifying the SROH-OHRQoL link. Considering the limited practical significance of education-OHRQoL, the role of education can be overlooked in similar population when using the OHIP scale.
