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
This study aimed to evaluate whether individuals who self-identify as black and/or mixed-race have a higher prevalence of tooth loss compared to white individuals in Brazil, using a systematic review and meta-analysis. Searches were conducted in the PubMed, Scopus, Web of Science, Virtual Health Library, Embase, and gray literature databases. Two independent reviewers performed the searches and article selection processes. The Newcastle-Ottawa Scale was used for observational cohort studies, and its modified version was used for cross-sectional studies. The I2 statistic assessed the heterogeneity of studies included in the meta-analyses. Of the 25 articles eligible for qualitative evaluation, 17 were included in the quantitative assessment. Sample sizes ranged from 101 to 18,718 individuals aged 11 to 74 years. Most studies compared white individuals to non-white individuals (black, mixed-race, Asian, and Indigenous people). In the comparison between white and non-white individuals, no differences were found concerning edentulism (OR = 0.86; 95%CI: 0.71; 1.06), absence of functional dentition (OR = 0.82; 95%CI: 0.33; 2.03), or mean number of missing teeth (MD = -0.21; 95%CI: -2.92; 2.49), but it was associated with tooth loss (OR = 1.40; 95%CI: 1.26; 1.55). When comparing black/mixed-race people to white individuals, tooth loss was higher among those who self-identified as black/mixed-race (OR = 1.41; 95%CI: 1.27; 1.57). This difference was also observed when comparing black/mixed-race individuals to other races/skin color (OR = 1.24; 95%CI: 1.15; 1.33). Overall, studies conducted in Brazil found that tooth loss was more prevalent among self-declared black and/or mixed-race individuals.
