Prevalence and determinants of Soil-Transmitted Helminths among urban vegetable farmers in Ghana.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionUrban vegetable farmers in Ghana face multiple health risks, including soil-transmitted helminths (STHs), which may contribute to morbidities that threaten urban food security. Additionally, infected farmers may act as persistent sources of disease transmission within urban populations. There is the need to assess the burden of STH among these farmers using more sensitive molecular assays.
methodsThis was a cross-sectional study involving 168 urban farmers from Accra and Tamale in Ghana's Greater Accra and Northern regions, respectively. Participants completed semi-structured questionnaires, and stool samples were collected for analysis. A qualitative Polymerase Chain Reaction (QPCR) assay was employed to detect STH prevalence, targeting the ITS1, ITS2, and 18S genes of Ascaris lumbricoides, Ancylostoma duodenale and Strongyloides stercoralis, respectively.
resultsWhile no positives were found in Tamale, 5.1%, 2.5%, and 0.8% of participants in Accra tested positive for A. lumbricoides, A. duodenale and S. stercoralis, respectively. Inadequate use of Personal Protective Equipment (PPEs) and STH infection status were strongly correlated among risk factors (Odds ratio; 4.3, 95% Cl: 1.03-18.00, p-value = 0.04). Overall, 72% of participants in Tamale wore PPEs, compared to 43% in Accra.
conclusionsEven though STH was not common, inadequate PPE use was a major factor in STH transmission in urban vegetable farms. Therefore, the key to drastically lowering the STH burden in urban farms is education and behaviour changes. Using more sensitive molecular diagnostic assays is crucial in low prevalence environments.
