Food environment components influencing consumption trends of neglected and underutilized species in northern Benin.
Article in PloS one, 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
Malnutrition is a global problem driven by food systems that impact climate and biodiversity. Neglected and underutilized species (NUS) could improve diets, but what drives their choices and consumption, particularly in low and middle-income countries, is poorly documented. This study investigated the influences of the personal food environment on the consumption of NUS in three communities in the department of Atacora in northern Benin. Following a purposive sampling strategy, 24 semi-structured interviews were conducted with locals and 18 with professional experts. 12 group discussions with villagers from six villages in the three communes complemented and deepened the information gathered, focusing on both barriers and factors for enhancing consumption. The data collected was translated and transcribed into French and analyzed using qualitative content analysis with Atlas.ti software. Among the investigated plant parts, an upward trend was found for Moringa oleifera leaves and Vigna radiata seeds, a downward trend for Adansonia digitata pulps, and a varied trend for Ocimum gratissimum leaves and Adansonia digitata kernels and leaves. Drivers for changes in consumption were found in all four dimensions of the food environment. Among the plant parts with the main increasing trend in consumption, various aspects of desirability, above all increased food and nutrition knowledge and skills, led to a positive consumption trend. The downward trend has most often been attributed to declining accessibility, but several aspects have also made these plant parts less affordable and less desirable (taboos for example). The strong variation in dimensions' influence on plant parts with variable trends reflects their non-unanimous changes. Research and policies should address the factors influencing the consumption of these foods. Making neglected species more accessible, affordable, and desirable can enhance food security and environmental sustainability.
