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
Leishmaniasis is an anthropozoonosis with vector transmission, and knowledge regarding the occurrence of this parasitosis in sentinels can contribute to infection and disease control measures in humans. The objectives of this study were to evaluate the occurrence of Leishmania exposure and infection in dogs from urban and rural areas in the North Pioneer Mesoregion of the state of Paraná, to evaluate possible risk factors, and to analyze the statistical agreement between the serological techniques that were used. Using a convenience sampling, serum and whole blood samples were collected to perform serological and molecular assays, respectively. The enzyme-linked immunosorbent assay (ELISA) and indirect fluorescent antibody test (IFAT) identified 29/204 (14.2%) and 20/204 (9.8%) seropositive dogs, respectively. Five dogs (2.4%) were seropositive for both serological tests, and four dogs presented high titers in the IFAT. None of the samples tested positive for Leishmania spp. DNA according to polymerase chain reaction analysis. No factors were significantly associated with infection. Leishmania parasites circulate in urban and rural dogs in the North Pioneer Mesoregion of the state of Paraná. Despite the absence of clinical cases, seropositive animals with high antibody titers should serve as a warning to the local population that should be properly informed regarding the prevention.
