Dental caries prevalence and caries-associated risk factors of students aged 12-15 in Xide County of Liangshan Prefecture, China: a cross-sectional study.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
objectiveAbout 2 billion people have caries in permanent teeth, and 514 million children have caries in primary teeth worldwide. Regional disparities in caries prevalence are evident in various areas of China. A comprehensive understanding of the status of dental caries and its associated risk factors is essential for developing effective dental health policies in economically disadvantaged regions. Thus, this study aims to examine the prevalence of dental caries and its risk factors among students aged 12-15 in Xide County, a remote mountainous area in China.
designIn this cross-sectional study, dental health surveys were conducted using self-administered questionnaires and the Decayed-Missing-Filled Tooth (DMFT) Index. An oral clinical examination was carried out by the criteria and guidelines set forth by WHO.
settingXide County, Liangshan prefecture, China in 2022.
participants558 students aged 12-15 years completed the survey.
resultsThe study conducted in Xide County found a dental caries prevalence of 42.5% among 12-15 year-old students, with a mean DMFT of 1.50 (SD=2.25). Multivariable logistic regression analysis identified several significant risk factors for dental caries (p<0.05), including starting brushing after the age of six (OR 0.34, 95% CI 0.17 to 0.65), brushing teeth less than once a day (OR 9.24, 95% CI 5.53 to 15.33) and consuming carbonated drinks more than once a day (OR 0.28, 95% CI 0.14 to 0.53). Additionally, the use of fluoride (OR 0.61, 95% CI 0.43 to 0.85) and awareness of its protective effect on teeth (OR 0.75, 95% CI 0.59 to 0.98) were found to be associated with a lower risk of dental caries (p<0.05).
conclusionThe prevalence of dental caries among students aged 12-15 in Xide County was identified as a significant public oral health concern. The oral health behaviours of students were found to be influenced by factors at the family and community levels.
