Seroprevalence and Associated Risk Factors of Brucellosis in Backyard Dairy Cattle in the Western Buffer Zone of Chitwan National Park, Nepal.
Article in Veterinary medicine and science, 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
introductionBrucella abortus, the etiological agent of bovine brucellosis, is a significant zoonotic disease of dairy cattle. The issue is particularly evident in Chitwan, one of the largest milk-producing districts in Nepal. MATERIALS AND
methodsEnzyme-linked immunosorbent assay (ELISA) was used to detect circulating antibodies against B. abortus in backyard dairy cattle in the western buffer zone of Chitwan National Park, Chitwan, Nepal.
resultsA total of 382 cattle, comprising Holstein-Friesian-cross and Jersey-cross breeds, were sampled; 6 were excluded from statistical analysis. Of the remaining 376 cattle, 6 (1.6%; CI: 0.59-3.44) tested positive for B. abortus. After adjusting for test specificity and sensitivity, the prevalence was estimated at 1.56%. No significant associations were found between higher antibody prevalence and risk factors such as sampling location, breeding technique, breed, age, parity, abortion, hygroma, repeat breeding and herd size. However, the presence of wildlife species in the buffer zone and low farmer awareness of zoonoses may contribute to persistent infection risks.
conclusionThese findings underscore the presence of bovine brucellosis in a key dairy region of Nepal and highlight the need for further investigation into the disease's epidemiology and its public health significance.
