Grocery Purchase Changes Were Associated With A North Carolina COVID-19 Food Assistance Incentive Program.
Article in Health affairs (Project Hope), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
Many low-income Americans experience food insecurity, which may have been exacerbated by economic instability during the early stages of the COVID-19 pandemic in 2020. In this study we assessed the impact of Healthy Helping, a short-term fruit and vegetable incentive program aimed at alleviating food insecurity and improving diet quality for Supplemental Nutrition Assistance Program participants, on grocery purchases, using transaction data from a large supermarket chain in North Carolina. We compared Healthy Helping participants' purchases of key food groups before and during the program with purchases by control shoppers participating in federal food assistance programs during the same period. Healthy Helping enrollment was associated with a $26.95 increase in monthly spending on fruit, vegetables, nuts, and legumes-an increase of 2.5 grams of fiber per 1,000 kilocalories purchased-and other shifts in the composition of food purchases, relative to control shoppers. These findings suggest that the program increased healthy food purchases while also increasing dollar sales at participating retailers. On average, participants did not use the full benefit; future research should explore factors associated with non- or underuse of benefits, to inform program design and outreach.
