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
methodsA cross-sectional study was carried out to determine the Seroprevalence and associated risk factors of small ruminant’s brucellosis in Borana Zone of Yabello and Elweye districts from November, 2024 to June, 2025. Different sampling methods were used to select the study districts, Peasant associations (PA), villages, householders and individual study animals. A questionnaire survey was administered to animal owners (pastoralists) from whose animal’s blood sample was collected.
resultsOut of 541 sera collected, 13 of them were seropositive for Brucella with an overall animal seroprevalence of 2.40%. Rose Bengal Plate test (RBPT) was used to screen the samples and Complement Fixation test (CFT) was employed on RBPT positives for confirmation. The study also revealed flock level seroprevalence of 14.29%. A statistically significant difference was observed between small ruminants with previous history of abortion and those without history of abortion (p = 0.002, OR = 7.88 with 95% CI: 2.20–28.23%). Similarly, Seropositivity for Brucella infection was significantly higher in small ruminants with more than three parities compared to those with zero or between one and three parities (p = 0.04, OR = 5.92; 95% CI: 1.07–32.58%). Regarding the knowledge of the interviewed pastoralists about brucellosis, more than 90% of them didn’t have any awareness about the zoonotic nature of brucellosis, control and prevention measures and had contacts with aborted fetuses and retained fetal membrane. CONCLUSION AND RECOMMENDATIONS: The finding confirms that the disease is circulating within the small ruminant population of the study areas and significant gaps in awareness and preventive practices among pastoralists. It is advisable to implement comprehensive control and prevention strategies aimed at reducing the incidence and impact of the disease and undertake community sensitization on public importance of the disease.
