Food environment in Brazil: food deserts and food swamps in large urban cities.
Article in Revista de saude publica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 assess the availability of healthy and unhealthy food establishments in Brazil and, thereby, map food deserts and food swamps. To analyze maps of food deserts and food swamps in conjunction with indicators of social inequality.
methodsData from the Relação Anual de Informações Sociais (RAIS, 2022), integrated with consumption profiles from the Pesquisa de Orçamentos Familiares (POF, 2017-2018), were used to classify establishments according to the Dietary Guidelines for the Brazilian Population. At the municipal level, the density of establishments with healthy and unhealthy profiles was estimated for Brazilian municipalities. At the intramunicipal level, food deserts and food swamps were identified in urban municipalities with more than 300,000 inhabitants, by cross-referencing the results with income indicators from the Cadastro Único.
resultsAt the municipal level, it was observed that the North and Northeast regions concentrate most municipalities with low densities of healthy establishments, while the South and Southeast have higher densities of unhealthy establishments. At the intramunicipal level, approximately 25 million people reside in food deserts, corresponding to 32.3% of the population of the 91 municipalities analyzed, and approximately 15 million live in food swamps (19% of the population). Among individuals in the Cadastro Único with a per capita income below half the minimum wage, 38% live in food deserts and 10% in food swamps.
conclusionThe results highlight the overlap between socioeconomic vulnerability and adverse food environments, reinforcing the urgency of public policies aimed at regulating the food environment, strengthening public food supply infrastructure, and promoting territorial equity in access to healthy foods.
