Purchases and prices of unprocessed or minimally processed foods according to food outlets and income in Brazil.
Article in Public health nutrition, 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 purchases and prices of unprocessed or minimally processed foods according to the type of food outlet and household income.
designCross-sectional study conducted with data from the 2017-2018 Brazilian Household Budget Survey. Food acquisition and income were the variables of interest. Unprocessed or minimally processed foods were identified according to the NOVA classification, and the shares of energy (kcal) and quantity (grams), as well as prices paid, were analysed. Food outlets were grouped into nine types. Household income per person was assessed in quintiles (Q). Descriptive analyses were conducted.
settingBrazil.
participantsA nationally representative sample of 57 920 households.
resultsThe amount of unprocessed or minimally processed foods acquired varied from 320 g (Q1 of income) to 493 g (Q5). The increase in income had a positive effect on the share of foods purchased in supermarkets (Q1: 27·6 % v. Q5: 63·8 %) and fruit and vegetable retailers (Q1: 1·5 % v. Q4: 4·6 %). In contrast, an inverse relation was observed for Mini-markets (Q1: 34·9 % v. Q5: 16·2 %), butchers (Q1: 6·8 % v. Q5: 2·3 %), street markets (Q1: 13·3 % v. Q5: 3·8 %) and street food vendors (Q1: 5·3 % v. Q5: 1·0 %). The price paid for unprocessed or minimally processed foods in supermarkets, mini-markets, butchers and street markets was positively associated with income, which means that a higher mean price was observed in the highest income quintile.
conclusionsThe availability and affordability of unprocessed or minimally processed foods differed according to food outlets and were influenced by income level.
