Severe tooth loss influences the perception of racial and gender discrimination among Brazilian older adults.

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 analyse whether severe tooth loss influences perceived racial and gender discrimination in Brazilian older adults.
methodsThe data were obtained from the Brazilian Longitudinal Study of Ageing, a nationally representative sample of community-dwelling individuals aged 50 and older. The outcome measured was the perception of discrimination in five different settings. The main explanatory variables were self-identified/self-perceived race (Whites and Non-whites) and gender, while covariates included education level, equivalized per capita income, depression, and the use of dental prostheses. Negative binomial and logistic regressions with interaction terms between race, gender and severe tooth loss were used to estimate the intersections between gender and race-related perceived discrimination inequities.
resultsThe analytical sample comprised 8,556 respondents with complete variables. While the prevalence of perceived discrimination in white Brazilians was 14.3% (95%CI: 12.2;16.3), it was 18.8% (95%CI: 16.8;20.6) among non-Whites. The interaction of being female, non-white and with severe tooth loss showed higher chances of perceived discrimination in 50-59 years [RR = 1.53(95%CI: 1.01;2.28)]. Moreover, being non-white with severe loss in 60-69 years [RR = 1.74(95%CI: 1.13;2.69)] had higher chances of perceived discrimination adjusted by all covariates. A sensitivity analysis of all older adults confirmed the findings.
conclusionsThe findings highlight the intersection between severe tooth loss, race, and gender, with more pronounced associations among women and non-white individuals. These results reinforce the importance of equity-oriented oral health policies and interventions within the Family Health Strategy, particularly for populations experiencing severe tooth loss.
