Mapping the Healthiness of Campus Food Environments in Nigeria: In-Store Retail and Outdoor Advertising Assessments at Selected Universities-The NigeFE Study.
Article in International journal of environmental research and public health, 2026. 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
The rising burden of obesity and non-communicable diseases among young people has prompted global recommendations for healthier food environments, but evidence is limited across African universities. This study aims to assess the healthiness and spatial distribution of university food environments using in-store retail audits and outdoor food advertising assessments. Outdoor food advertisements were audited in two universities (excluding the University of Ibadan), while retail stores were assessed across three participating institutions within a 300-500 m radius of each campus. Data were collected using the INFORMAS protocol and the NEMS-S-MED in-store audit tool, respectively, alongside spatial analyses. A total of 76 food advertisements and 145 food retail stores were identified. Less than one-tenth (7.5%) of advertised products were healthy. Healthier foods in retail stores were predominantly characterised by moderately low (37.2%) and medium (31.7%) availability, while affordability was low (73.1%), resulting in over half being classified as having a low (51.7%) degree of healthiness. These differed significantly across institutions (
