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
Triatomines of the genus Rhodnius are of high epidemiological relevance in Brazil, being predominantly found in wild environments, especially in palm trees and nests. The aim of this study was to report, for the first time, the occurrence of Rhodnius nasutus in the domestic environment of the urban area of the municipality of Barra, Bahia. R. nasutus was collected inside an urban residence at different times, one female and one male. Coprological analysis indicated the presence of flagellated forms suggestive of Trypanosoma cruzi only in the female specimen. The presence of R. nasutus, a species typically associated with wild ecotopes of the Caatinga biome, reinforces its ability to disperse to transition areas between Caatinga and Cerrado, such as the municipality of Barra. This unprecedented record highlights the need for further investigation into food sources, dispersal capacity, and the species' potential for adaptation to the domestic environment.
