Healthfulness of street food outlets around public schools in Mexico.
Article in BMC public health, 2025. 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
backgroundDisparities in the availability, distribution, and density of formal unhealthy and healthy food outlets around schools have been observed based on sociodemographic neighborhood characteristics; however, little is known about street food outlets (SFOs).
objectiveTo analyze the spatial characteristics of healthy and unhealthy SFOs around public schools in a Mexico City neighborhood and their association with environmental factors. METHODOLOGY: A cross-sectional study was conducted to identify SFOs located within a 500-meter buffer around 67 public schools situated in a neighborhood with diverse levels of marginalization in Mexico City. The nutritional healthfulness index (NH-index)-defined as the percentage of available healthful food and beverage groups-was calculated for each SFO using a validated tool for the Mexican context. Logistic regression analyses were performed to estimate the association between null healthfulness (null-NH), defined as 0% availability of healthy food groups, and environmental characteristics. Additionally, spatial analyses were conducted to examine the distribution and density of SFOs around schools.
resultsIn total, 1296 SFOs were identified within 500 m around schools. In total, 42.4% of them were classified as unhealthy. SFOs located in areas with a very high SDI, farther from schools, and with a higher total population per block were less likely to be classified as null-NH.
conclusionsUnhealthy street food outlets are highly concentrated near public schools in vulnerable areas of Mexico City. While new regulations aim to reduce exposure to these products, further research is needed to evaluate their impact.
