1 · What the graph read from it

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.

2 · The registry

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

backgroundIn Sub-Saharan Africa, post-harvest loss (PHL) of fruits and vegetables significantly contributes to food and nutrient insecurity. Although PHL has an economic impact, the nutritional implications of PHL throughout the food supply chain remain largely unexplored. This research aimed to identify the causes of PHL in the Ho West District of Ghana and estimate the associated nutritional losses.

methodsThe study adopted a cross-sectional mixed-methods design, involving 299 respondents (81 farmers, 81 traders, and 137 household women). Data were collected using structured questionnaires and focus group discussions. Post-harvest losses were categorised as high or low based on the distribution of reported losses and analysed using chi-square tests, ANOVA, and regression models to identify key drivers. Nutritional losses were calculated using adapted protocols from the World Bank and WBCSD Food Loss and Waste Protocol, focusing on key nutrients such as iron, vitamin A, and vitamin C.

findingsKey drivers of PHL included age, education, income level, poor storage, transportation delays, and the length of time produce remained unsold. Nutritional loss estimates revealed substantial iron, vitamin A, and vitamin C losses at the retail and household levels; these losses were converted into equivalent daily requirements for women and children based on standard recommended dietary allowances, assuming complete nutrient loss once produce became unfit for consumption. At the household level, vitamin C losses averaged 4.6 mg per 100 g of edible portion of fruits and vegetables lost, based on standard food composition values. Thematic analysis revealed inadequate knowledge of storage, limited preservation tools, and misconceptions about food spoilage.

conclusionPost-harvest handling practices, socio-demographic factors, and lack of awareness contribute to significant nutrient losses across the fruit and vegetable value chain. Interventions should focus on training, household-level preservation techniques, and improved infrastructure to reduce nutritional losses and support food security.
