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 investigate the association between individual and contextual variables and lack of access to dental services among the Brazilian adult population.
methodsThis is a cross-sectional study based on a nationally representative sample of adults aged 35 to 44 years from SB Brasil 2023. Multiple analyses were performed using multilevel logistic regression. The outcome was lack of access to dental services. Individual exposures included demographic data, income, educational attainment, and type of service sought; contextual variables included population size, socioeconomic development, and availability of public dental services in Brazilian cities.
resultsIt was found that 17.5% of Brazilian adults did not receive dental care when they sought it. Low educational attainment, low family income, and seeking public services increased the likelihood of lack of access. The contextual variables did not explain the outcome, in addition to the individual-level factors.
conclusionLack of access to dental services among adults in Brazil was associated with low socioeconomic status and with those who sought public services, considering contextual variables related to the municipalities included in the study. The absence of an association between the contextual variables analyzed and lack of access may reflect the widespread availability of dental services, an extremely positive aspect of the Brazilian health system. Nevertheless, despite advances in expanding coverage and the establishment of the Política Nacional de Saúde Bucal (National Oral Health Policy) as a state policy, socioeconomic inequalities persist that limit the principle of equitable access.
