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
objectiveTo determine the prevalence and factors associated with negative self-assessment of oral health among adolescents living in the Southeast region of Brazil.
methodsThis is a cross-sectional study using data from the National Oral Health Survey of 2003 and 2023. Through examination and questionnaire, clinical, socioeconomic, and oral health perception data were obtained from 2981 individuals in 2003 and 919 in 2023. Descriptive, bivariate, and multivariate analyses were performed using Poisson regression with robust variance.
resultsNegative self-assessment of oral health was observed in 43.9% (95% confidence interval - 95%CI 38.7-49.1) of participants in 2003 and 33.4% (95%CI 27.2-40.3) in 2023. In the multivariate analysis, the factors associated with worse self-assessment of oral health were: being 18 or 19 years old (prevalence ratio - PR 1.04; 95%CI 1.01-1.08 in 2003 and PR 1.27; 95%CI 1.00-1.63 in 2023), not owning a home (PR 1.16; 95%CI 1.01-1.32 in 2003), receiving government assistance (PR 1.40; 95%CI 1.11-1.77), feeling the need for treatment (PR 2.7; 95%CI 1.94-3.74 in 2003 and PR 3.0; 95%CI 1.58-5.70 in 2023), experiencing toothache (PR 1.67; 95%CI 1.38-2.04 in 2003 and PR 1.72; 95%CI 1.17-2.54 in 2023), having dental calculus (PR 1.22; 95%CI 1.04-1.43 in 2003 and PR 1.84; 95%CI 1.28-2.66 in 2023), having missing, decayed or filled teeth (PR 1.02; 95%CI 1.01-1.04 in 2003), loosing teeth due to cavities (PR 2.19; 95%CI 1.42-3.37 in 2023), and last visiting the dentist two to three years earlier (PR 1.89; 95%CI 1.39-2.56 in 2023).
conclusionA high prevalence of negative self-assessment of oral health was observed among adolescents in the Southeast region, a finding associated with a multidimensional structure of variables.
