Gastrointestinal parasites in pigs in Brazil: prevalence, risk factors, diagnosis, and extension activities.
Article in Parasitology research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Brazil is a major pig-producing country with production systems that include both industrial and family farms. In these facilities, parasitic diseases present an obstacle to production. This study aimed to estimate the prevalence and risk factors of the gastrointestinal parasites that infect pigs as well as to provide information for producers through extension activities. Visits were made to 15 pig farms in cities in the states of Rio de Janeiro and Minas Gerais. Fecal samples were collected, questionnaires administered, and extension activities conducted. A total of 1,148 samples were collected: 299 from family farms and 849 from industrial farms. Stool samples were subjected to direct examination, sedimentation, flotation, and FLOTAC techniques. The most frequently detected parasites were cysts and trophozoites of the Ciliophora group, non-sporulated coccidian oocysts, eggs of Trichuris suis, strongyles, Strongyloides ransomi, and Ascaris suum. Statistical analysis revealed significant differences (p ≤ 0.05) in parasite presence and egg counts, with family farms exhibiting higher parasite burdens (p < 0.0001). Several risk factors were associated with the frequency of parasite infection, including the arrangement of watering systems on the pen floors and the type-or absence-of antiparasitic medication provided. Among the extension activities implemented, the "happy pig and sad pig" activity and "homework correction" stood out. These results highlighted the need for improvements in national pig production. This includes the development of programs offering credit, assistance, and training for pig producers to aid in the control of these parasites, with a focus on production and animal welfare.
