First identification of Lutzomyia longipalpis in an area of visceral leishmaniasis transmission in central Rio Grande do Sul State, southern Brazil.
Article in Parasitology research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Sand flies are hematophagous dipterans and are considered vectors of the parasites belonging to the genus Leishmania, which can infect mammals, including humans, and subsequently cause leishmaniasis. Rio Grande do Sul State (RS), southern Brazil, was considered free of this disease for the last few decades. However, several autochthonous cases of visceral leishmaniasis (VL) have been recorded in different municipalities in recent years. Since 2017, cases of canine visceral leishmaniasis (CVL) have been reported in the municipality of Santa Maria, located in the central region of RS. In 2021, two cases of human VL were confirmed in the city, resulting in one death. To capture the possible vectors involved in the disease transmission cycle, Centers for Disease Control (CDC) modified light traps were installed in the peridomestic residential areas. These points were situated in two city districts where cases of CVL had been reported from January 2021 to January 2022. In the 41 sample collections of sand flies, 9 specimens of Lutzomyia longipalpis were identified, confirming the municipality as an area of VL transmission, according to Brazilian sanitary standards. The spread of Leishmania spp. has been occurring efficiently, resulting in a negative impact on the One Health. This study reports the first detection of L. longipalpis in the central region of RS.
