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
objectiveTo describe the prevalence and distribution of canine leishmaniasis and the phlebotomine fauna across the five urban neighborhoods of the Cachoeira do Piriá Amazonian municipality, Pará state, Brazil, during the dry season.
methodsDogs were sampled for five hours in each neighborhood, with blood and conjunctival swab specimens (from June 13 to 15, 2023). Samples were tested using polymerase chain reaction targeting the heat shock protein 70-234 gene. Risk areas (kernel) and phlebotomine fauna were investigated (from 1 to 7/10/2023).
resultsA total of 93/864 (11%) animals were included. The prevalence of canine leishmaniasis was 65% (60/93). Positivity rates varied among neighborhoods (p-value 0.001), with major clusters in the Northwest and Southeast urban areas, encompassing three neighborhoods. Lutzomyia antunesi (2) and Lutzomyia evandroi (11) were found in four neighborhoods.
conclusionHigh prevalence of canine leishmaniasis and a potential phlebotomine vector (Lutzomyia antunesi) were identified during the Amazonian summer in the urban area of Cachoeira do Piriá, where three neighborhoods were prioritized for surveillance.
