Climate-driven disruptions in local food systems and the transmission pathways of food-borne neglected tropical diseases in Sub-Saharan Africa: a scoping review.
Article in BMC 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
backgroundClimate change increasingly disrupts food systems in Sub-Saharan Africa, yet the implications for food-borne neglected tropical disease (NTD) transmission remain poorly synthesised.
aimTo map and synthesise evidence on how climate-driven disruptions in local food systems influence transmission pathways of food-borne NTDs in Sub-Saharan Africa.
methodsA scoping review was conducted in accordance with PRISMA-ScR guidelines and five electronic databases (PubMed/MEDLINE, Scopus, Web of Science, Embase, and African Journals Online) were searched from inception up till January 31st 2026. Peer-reviewed primary studies examining climate-related disruptions to food systems and food-borne NTD transmission in Sub-Saharan Africa were included. Data were charted and synthesised thematically.
resultsTwenty studies were included and five key themes emerged: climate variability as a driver of food system vulnerability; food system stages as critical transmission nodes; behavioural and socioeconomic mediators; zoonotic and environmental interfaces; and structural gaps in surveillance, policy, and interventions. Climate-related stressors consistently disrupted food production, storage, distribution, and preparation, increasing exposure to food-borne NTDs.
conclusionClimate-driven food system disruptions represent a critical but under-recognised pathway for food-borne NTD transmission. Integrating food system resilience into climate adaptation and NTD control strategies is essential for reducing disease burden in Sub-Saharan Africa.
