Prevalence of dental caries and influence factors among students in Beijing: A cross-sectional study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe burden of dental caries continues to be substantial worldwide, significantly affecting adolescents and children's growth and quality of life. This study aimed to explore the epidemiological characteristics of dental caries and examine influencing factors that contribute to caries among children and adolescents in Beijing.
methodsA total of 21,403 students (average age 12.8 ± 2.5 years old) were included in this cross-sectional survey. The DMFT/dmft index (decayed (D), missing (M), and filled (F) teeth) was used for screening. Multistage stratified random cluster sampling methods were conducted in primary and secondary schools in Beijing in 2021. Data were collected using questionnaires and assessed using a logistic regression analysis. Statistical significance was set at P < 0.05.
resultThe overall prevalence of caries was 40.5% (95% CI: 39.8-41.1%). The mean score of DMFT was 1.31 ± 2.11, and the mean score of dmft was 0.39 ± 1.24. Among participants, girls, students in lower grades, those of younger ages, and those with lower BMI levels were more likely to experience dental caries. A multivariate logistic regression analysis identified the following variables as predictors of an increased risk for caries experience: residing in boarding school (odds ratio [OR]=1.15); coming from a rural area (OR = 2.55); frequent consumption of sugary beverages (ORmax = 1.23), and fresh fruit (ORmax = 1.35); breakfast irregularity (ORmax = 1.22); infrequent tooth brushing (ORmax = 1.16); and longer sleep duration (ORmax = 1.30).
conclusionsDental caries, widely prevalent among children and adolescents in Beijing, is associated with dietary habits, hygiene practices, and sleep patterns. To effectively mitigate its burden, prevention strategies targeting these identified risk factors should be prioritized.
