Entomological findings in a focus of visceral leishmaniasis transmission in Embu das Artes Municipality: Contributions for prevention and surveillance.
Article in Revista da Sociedade Brasileira de Medicina Tropical, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLeishmaniasis occurs in Embu das Artes, where Lutzomyia longipalpis is absent, but secondary vectors are present.
methodsSandflies were collected using Shannon and CDC (Center for Disease Control) light traps in a household with seropositive dogs; presence of flagellates was investigated by dissection.
resultsFrom 11 species, 1,224 sand flies were collected, predominantly Pintomyia (Pi.) fischeri (88.6%) and Migonemyia (Mg.) migonei (8.4%). Shannon traps captured most specimens, mainly in peridomicile. Abundance was higher during spring/summer. Flagellates were detected only in Evandromyia (Ev.) edwardsi, with a 0.13% overall infection rate.
conclusionPi. fischeri predominance and kennel association of Mg. migonei reinforce their epidemiological importance for local leishmaniasis transmission.
