1 · What the graph read from it

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.

2 · The registry

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

backgroundThis study investigated the relevant factors influencing the caries increment among schoolchildren in Liaoning Province and constructed a structural equation model to analyze the complex interrelationships among these factors.

methodsBaseline data of 7,904 schoolchildren were collected through clinical oral examinations and questionnaire surveys in 2024 and oral examinations for the cohort were collected in 2025.

resultsThe prevalence of dental caries was 31.1% in 2024, with a mean DMFT/dmft of 0.84 ± 1.57, which increased to 50.6% and 1.63 ± 2.24, respectively, in 2025. A total of 2,865 individuals showed caries increment (defined as △DMFT/dmft ≥ 1), corresponding to an incidence of 36.2%. The results of the multivariate logistic regression analysis indicated that socioeconomic region, grade, gender, weight status, and deliberate exclusion from or isolation in group activities were significantly associated with the caries increment. Structural Equation Modeling analysis (SEM) converged to identify socioeconomic factors as a factor associated with caries incidence, showing both direct associations and indirect associations mediated by poorer dietary habits, although the observational one-year design precludes strong causal clclaims. Notably, the model also indicated a protective association with higher weight status, a finding that merits further investigation.

conclusionsWhile conventional factors such as socioeconomic status, dietary habits, and weight status are well-established influencers of caries increment in schoolchildren aged 9-12, our findings highlight that psychological factors, such as experiences of social isolation, constitute a significant determinant. This dimension merits particular attention in both future research and preventive strategies.
