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
backgroundTriatoma vitticeps (Stål, 1859), a primarily sylvatic vector of Trypanosoma cruzi (Chagas, 1909), has been reported invading dwellings and peridomiciliary ecotopes in several regions of Brazil. OBJECTIVES AND
methodsHere, we report for the first time, the colonisation of a brick house by T. vitticeps in the municipality of São José do Vale do Rio Preto, Rio de Janeiro State.
findingsInside the house, indicators of colonisation were recorded, including 15 eggs, 11 nymphs, two exuviae, and 19 adult specimens. T. cruzi infection was detected in 13 specimens and the blood meal source identification, through amplification of DNA fragments indicated the presence of human blood as one of the feeding sources in seven specimens. MAIN
conclusionsThe infested dwelling was treated with insecticide to control the infestation, and residents were appropriately instructed to remain vigilant for the presence of triatomines and to contact health authorities if new specimens were detected.
