Recurrent aphthous stomatitis (RAS) and its related factors among the Azar cohort population.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionRecurrent aphthous stomatitis (RAS) is one of the most prevalent oral inflammatory ulcerative lesions, characterized by painful ulcers that develop on non-keratinized oral mucosa, significantly affecting the quality of life. This study aimed to evaluate the prevalence of RAS and its associated risk factors within the Azar cohort population.
methodsThis cross-sectional study utilized data from the Azar cohort, which has been ongoing since 2014 in Shabestar City, East Azarbaijan, Iran, involving 15,006 adults aged 35 to 70 years. To assess the prevalence of RAS, participants were provided with a description of these lesions and asked whether they had ever experienced RAS in the oral cavity. Data collection was based on self-reports and examinations conducted by the physicians involved in the Azar cohort. Participants with RAS were classified into the RAS group, while the remaining participants were categorized into the non-RAS group. We assessed the association between RAS and various factors using binary logistic regression.
resultsIn the study population, there were 3,503 individuals in the RAS group and 11,503 individuals in the non-RAS group. The prevalence of RAS in the Azar cohort was 23.34%. Individuals over 50 years of age (p < 0.001), those with a poor (p < 0.001) or very poor (p = 0.02) socio-economic status, a low educational level (p = 0.01), smokers (p < 0.001) and individuals with a history of smoking who have since quit (p = 0.01) were significantly less affected by RAS. Conversely, individuals with genital aphthous lesions (p < 0.001), depression (p < 0.001), rheumatoid disease (p = 0.01), and food allergies (p < 0.001) were significantly more affected by RAS.
conclusionsFactors such as being under 50 years of age, possessing a high socioeconomic status, having a higher level of education, experiencing genital aphthous disease, suffering from depression, having rheumatoid disease, and having food allergies may be associated with a higher prevalence of RAS.
