Territorial inequalities in the food environment of Brazilian metropolitan regions.
Article in Revista brasileira de epidemiologia = Brazilian journal of epidemiology, 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 describe the retail food environment of Brazilian metropolitan regions using intramunicipal socioeconomic indicators, applying the Locais-NOVA classification.
methodsData from the 2023 Annual Social Information Report were used, with Human Development Units (HDUs) as the unit of analysis. Food establishments were geocoded and assigned to HDUs. The Locais-NOVA methodology was applied, which classifies food acquisition outlets according to the degree of food processing and proposes five food environment indicators. The percentage of each indicator was calculated for HDUs and stratified into tertiles of the Municipal Human Development Index (MHDI), considering the distribution of HDUs, Brazilian macroregions, and capitals versus non-capitals. A food environment healthiness indicator was created to measure the competition between healthy and unhealthy outlets and was used for spatial description through maps.
resultsA total of 8,977 HDUs across 24 metropolitan regions were assessed, with a mean MHDI of 0.76 and an average of 42.8 food establishments per HDU. Most food outlets were classified as sources of ultra-processed foods (64.9%), with a higher proportion in the first MHDI tertile (67.5%) compared with the third tertile (63.1%). A lower presence of outlets sourcing fresh and minimally processed foods was observed in the first MHDI tertile compared with the third (25.8 vs. 32.3%). The Southeast showed the highest percentage of outlets sourcing processed foods (17.3%). Non-capital concentrated a higher proportion of outlets sourcing processed foods compared with capitals.
conclusionA high prevalence of outlets sourcing ultra-processed foods was observed, particularly in territories with worse socioeconomic conditions.
