Changes in the food environment surrounding schools in four New Jersey school districts between school years 2012-13 and 2019-20.

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
objectivesWhile public health policies have mostly targeted the food environment within schools, recent research shows that the food environment surrounding schools is also related to children's diet and health outcomes. The goal of this paper was to examine the changes in the food environment around schools from school year 2012-13 to 2019-20 in four New Jersey school districts.
methodsWe analyzed data from 152 kindergarten - 12th grade public schools in Camden, Newark, New Brunswick, and Trenton for 2012-13 to 2019-20. Food outlets within 0.25-mile buffers around schools were classified into convenience stores, limited-service restaurants, small grocery stores, and upgraded convenience stores. Multivariable Poisson and negative binomial regression models were used to evaluate trends in food outlet prevalence over the study period.
resultsThe number of convenience stores decreased by 6 % annually (exp(βi) = 0.94, 95 % CI: 0.91; 0.96), while the number of upgraded convenience stores (carrying a selection of healthier items) increased by 30 % annually (exp(βi) = 1.30, 95 % CI: 1.17; 1.44). Other outlet types, such as small grocery stores and limited-service restaurants, remained stable.
conclusionsAlthough unhealthy outlets remained the most prevalent, there were improvements in the food environment around schools over the study period. Notably, these changes coincided with local policy initiatives aimed at improving healthy food offerings in convenience stores. Local policies can improve the food environment around schools by increasing access to healthier options. Policies aimed at improving the food environment around schools are crucial for supporting children's health and enhancing the effectiveness of school nutrition programs.
