Risk and protective factors of Leishmaniasis in the rural area of the western border region of Rio Grande do Sul, Brazil.
Article in BMC veterinary research, 2021. 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
backgroundThe Leishmaniases are on the top of the global list of tropical neglected diseases. The number of infected dogs in South America is estimated in millions and correlated to disease cases in humans, especially in Brazil. Equines may get infected too and can play a role in the epidemiological chain. Thus, the aim of the present study was to evaluate risk and protective factors of leishmaniasis in rural areas of the western border region of Rio Grande do Sul state, Brazil by Leishmania spp. protozoa molecular detection and serological evaluation (ELISA) in equine and canine blood samples. This work included nine farms around the city of Uruguaiana. Epidemiologic information regarding farm characteristics and biologic material collection of canine (22) and equine (91), totalizing 113 samples was collected. The polymerase chain reaction (PCR) technique was used to detect Leishmania spp. in biological samples. Variables related to the farm were collected and evaluated through descriptive analysis followed by chi-square test and a logistic regression analysis.
resultsNineteen positive samples (19/113 - 16,81%) were detected, being 18 equines and 1 canine, in six of the nine farms included in the study. No animal showed clinical signs of the disease. According to the variables analyzed, when compared each characteristic separately, the presence of abundant vegetation and poor hygiene demonstrated to be risk factors to Leishmania infection in rural areas. The logistic regression showed that excellent general hygiene, proximity to the weir and trimmed grass were protective factors (p=0.038, p=0.001 and p=0.014, respectively). Having excellent hygiene represents a 70% lower chance of getting infected, keeping the grass cut protects the animal by more than 90% and the proximity of the weir represents a protective factor of 96%.
conclusionsThe presence of Leishmania infection in the western border region of Rio Grande do Sul was 16,81% and it was influenced by farm characteristics. The role of the excellent general hygiene as a protective factor is extremely relevant in the leishmaniases prevention.
