Intestinal Parasitic Infections (IPIs) and Contributing Factors in Bovine Calves in Southern Nepal.
Article in Veterinary medicine and science, 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
backgroundIn Nepal, cows and buffaloes are common livestock used in subsistence farming and are often afflicted by helminth and protozoan parasites.
objectivesThis study aimed to evaluate the prevalence of intestinal parasitic infections (IPIs) and contributing (i.e., previously suggested to be associated with IPIs) factors affecting bovine calves in the Birgunj region, Nepal.
methodsFrom June to December 2023, 200 faecal samples (100 from commercial farms and 100 from subsistence farms) were collected and analysed using flotation and sedimentation techniques. Contributing factors were systematically obtained using structured questionnaires and direct field observations.
resultsOverall, 62% of the samples contained oocysts or eggs of intestinal parasites. The identified species included one protozoan (Eimeria spp., 7.5%), five nematodes (Strongyloides spp., 15.5%; Ostertagia spp., 6.5%; Haemonchus spp., 4.5%; Toxocara spp. and 11.5%; Ascaris spp., 4%) and two trematodes (Fasciola spp., 20%; Paramphistomum spp., 13%). The Fasciola spp. prevalence was notably higher in calves from subsistence farms compared to commercial farms (p = 0.015). Buffalo calves presented higher rates of Fasciola spp. and dual infections (p = 0.001), whereas cow calves presented a greater prevalence of Toxocara spp. (p = 0.046). Calves grazing near riverbanks presented significantly higher odds (adjusted odds ratio [aOR]: 2.76, 95% confidence interval (CI) [1.07-7.14]) of any IPIs, even after adjusting for other significant factors in a bivariate model. Factors, such as free-range rearing, subsistence farming and grazing on riverbank grasses, were linked to higher odds of Fasciola spp. infection in the bivariate model, but only the presence of buffalo calves ([aOR]: 2.64, 95% CI [1.03-6.76]) remained significant after mutual adjustment (i.e., in the multivariate model).
conclusionsThese findings underscore the significant burden of intestinal parasites in young calves, highlighting the need for regular inspections and preventive measures.
