Prevalence of bovine hydatidosis in Ethiopia: a systematic review and meta-analysis.
Synthesis in BMC veterinary research, 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
Bovine hydatidosis, caused by the larval stage of Echinococcus granulosus, remains a major parasitic disease affecting cattle and the meat industry in Ethiopia. This study aimed to estimate the pooled prevalence of bovine hydatidosis in Ethiopia through a systematic review and meta-analysis. A systematic search of PubMed, Google Scholar, African Journals Online (AJOL), and Science Direct was conducted to identify studies published between January 2013 and May 2023. The methodology followed the PRISMA 2020 guidelines. A total of 60 eligible cross-sectional studies reporting prevalence of bovine hydatidosis in Ethiopia were included. Data were extracted using a standardized template and appraised using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Prevalence Studies. Pooled prevalence estimates were calculated using STATA 14 with a random-effects model, applying logit transformation to stabilize variances. Heterogeneity was evaluated using Cochran's Q test and I² statistics, and publication bias was assessed with Egger's test and funnel plots. The pooled national prevalence of bovine hydatidosis was 27.4% (95% CI: 24.3-30.5) with significant heterogeneity (I² = 97.7%, p < 0.001). Subgroup analyses revealed higher prevalence in eastern Ethiopia (32.0%, 95% CI: 19.3-44.7) and lower in northern Ethiopia (23.7%, 95% CI: 19.9-27.6). No significant temporal trend was observed across the study period. Funnel plots and Egger's test (p = 0.32) indicated no publication bias. This systematic review and meta-analysis reveal that bovine hydatidosis remains endemic and widespread in Ethiopia, with marked regional variability. Strengthened abattoir inspection, dog deworming, and improved offal disposal practices are essential to reduce infection risk.
