Differences in a Chain Supermarket's Sales to SNAP Shoppers Before and Since the COVID-19 Pandemic.
Article in Journal of nutrition education and behavior, 2023. 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
objectiveThis study 1) compares grocery sales to Supplemental Nutrition Assistance Program (SNAP) shoppers in rural and urban grocery stores and 2) estimates changes in sales to SNAP shoppers in North Carolina (NC) since the pandemic.
designWeekly transaction data among loyalty shoppers at a large grocery chain across NC from October 2019 to December 2020 (n = 32; 182 store weeks) to assess nutritional outcomes.
settingNorth Carolina large chain grocery stores.
participantsLarge chain grocery store/SNAP shoppers.
interventionRural/urban status of the stores and COVID-19 pandemic onset.
main outcome measuresShare of total calories sold from fruits, vegetables, nuts, and legumes (FVNL) with and without additives, sugar-sweetened beverages (SSB), less healthful foods (LHF), and processed meats (PM). ANALYSIS: Multivariate random effects models with robust standard errors to examine the association of rural/urban status before and since coronavirus disease 2019 with the share of calories sold to SNAP shoppers from each food category. We controlled for county-level factors (eg, sociodemographic composition, food environment) and store-level factors.
resultsWe did not find significant rural-urban differences in the composition of sales to SNAP shoppers in adjusted models. There was a significant decrease in the mean share of total calories from sugar-sweetened beverages (-0.43%) and less healthful food (-1.32%) and an increase in the share from processed meats (0.09%) compared with before the pandemic (P < 0.05). CONCLUSIONS AND IMPLICATIONS: Urban-rural definitions are insufficient to understand nuances in food environments, and more support is needed to ensure healthy food access.
