[Food environment and excess weight in schoolchildren: a South American systematic reviewAmbiente alimentario y exceso de peso en la población escolar: revisión sistemática en América del Sur].

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
Objective: To identify and compile the findings of observational studies analyzing the relationship of factors from the school food environment and individual factors related to food consumption in school with excess weight in schoolchildren from South America in the period from 2011 to 2021. Method: The literature review involved a search performed in five databases (PubMed, Web of Science, SciELO, Scopus, and LILACS) and in Google Scholar, as well as a consultation with specialists. Studies were selected if they had an observational design, included schoolchildren aged 5 to 19 years, were performed in South America, and used objective measures such as body mass index (World Health Organization and/or International Obesity Task Force) to assess weight in association with school food environment factors and individual school consumption factors. The protocol was registered in PROSPERO (CRD42020212383). Results: Of 906 identified records, 13 cross-sectional studies (one from Argentina, one from Ecuador, and 11 from Brazil) were included in the review. The prevalence of overweight ranged from 7.5% to 32.5%, and of obesity, from 1.7% to 28.0%. School environment factors from the policy and physical domains (such as unsatisfactory food and nutrition education and unavailability of school-prepared meals) were associated with increased prevalence of excess weight. Individual factors related to adherence to the school meal program (such as consumption of meals offered by the school instead of bringing a snack from home) were associated with lower prevalence of excess weight. Conclusions: Only a few studies are available in South America with a focus on individual and/or school food environment factors and excess weight in schoolchildren. Since the available evidence is restricted to local or regional contexts, new national-level studies are warranted.
