Prevalence and risk factors of sheep and goats fasciolosis in Ethiopia: A systematic review and meta-analysis.
Synthesis in PLoS neglected tropical diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundFasciolosis is a parasitic disease caused by liver flukes of the genus Fasciola, predominantly Fasciola hepatica and Fasciola gigantica. This zoonotic disease significantly impacts both livestock and human populations, particularly in areas with extensive agriculture and poor sanitation. Ethiopia, one of Africa's leading sheep and goats producers, is highly affected by fasciolosis. However, despite its economic and public health importance, there is a lack of comprehensive and up-to-date evidence on the prevalence and risk factors of small ruminant (sheep and goats) fasciolosis. Therefore, the objective of this systematic review and meta-analysis (SRMA) is to estimate pooled prevalence and identify risk factors of fasciolosis among small ruminants in Ethiopia.
methodsThis SRMA was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive systematic review was performed across five electronic databases (Google Scholar, Embase, PubMed, Web of Science, and ScienceDirect), with all database searches and registers inquiries finalized on November 26, 2024. A random-effect model was used to determine the pooled prevalence of fasciolosis in sheep and goats. Heterogeneity was assessed, and the source of variation was analyzed using subgroup, sensitivity analysis and meta-regression. Publication bias assessment and sensitivity analysis were also performed to ensure the robustness of the review. Funnel plots and Egger's asymmetry tests were used to investigate publication bias.
resultsA total of 33 studies containing 9,578 small ruminants were included in the meta-analysis. The overall pooled prevalence of fasciolosis was 32.25% (95% CI: 25.97-38.86%) with substantially high between-study heterogeneity (inconsistency index (I2)) = 97.3%, p < 0.01). Among the variables analyzed for heterogeneity, species, publication years, season of data collection, and regions of the study were significant predictors of heterogeneity The sub-group analysis showed that the prevalence of fasciolosis among sheep and goats was 37.18% (95% CI; 31.06-43.51%) and 12.76% (95% CI; 4.06-25.19%), respectively. According to the region-based subgroup analysis, studies taken from Amhara region had the highest prevalence of fasciolosis among small ruminants (43.99% (95% CI: 31.83-56.52%)).
conclusionThis study highlights fasciolosis as a significant threat to Ethiopian small ruminants. Policymakers and veterinarians should prioritize evidence-based control programs in regions with high disease burden, through seasonal deworming, pasture rotation to disrupt snail ecology, and improved veterinary access in underserved areas.
