Dental Caries and Associated Factors in Tibetan School-Age Children in Gannan, China.
Article in International dental journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
objectivesData on the oral health status in the Qinghai-Tibetan Plateau are limited. This study aimed to investigate the dental caries status and identify associated risk factors among 8- to 12-year-old children in Gannan, a Tibetan Autonomous Prefecture in Northwest China.
methodsThe study population was recruited using a multistage stratified random sampling procedure. Caries status was assessed by clinical oral examination and indicated by the decayed, missing, and filled teeth (DMFT/dmft) index. Information on sociodemographic characteristics, oral hygiene behaviours, and dietary habits was collected using a comprehensive structured questionnaire. Statistical analyses, including the chi-square test and a two-level logistic regression model, were conducted to examine the risk factors associated with dental caries.
resultsA total of 1024 Tibetan children were examined, revealing a dental caries prevalence rate of 89.55%, with a mean DMFT/dmft index of 4.25 ± 3.27. The two-level logistic regression model showed that initiating tooth brushing at four to 5 years old (OR = 2.295, 95% CI 1.053-5.002) and frequent dessert and candy intake (OR = 2.655, 95% CI 1.216-5.794) were risk factors for dental caries. Conversely, being 11 years (OR = 0.399, 95% CI 0.177-0.904) or 12 years old (OR = 0.396, 95% CI 0.163-0.961) and if the father's education level was high school or above (OR = 0.311, 95% CI 0.098-0.986) were indicated to be protective factors against dental caries.
conclusionsThe prevalence of dental caries was high in Tibetan children aged 8 to 12year-old in Gannan. Therefore, it is imperative to prioritize comprehensive home- and school-based interventions to improve the oral health of this population.
