Fauna and seasonality of sand flies (Diptera: Psychodidae: Phlebotominae) from a leishmaniasis transmission area in the central region of Rio Grande do Sul, Brazil.

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, vectors capable of transmitting Leishmania spp. and causing leishmaniasis, have been a concern in the central region of Rio Grande do Sul, where canine leishmaniasis (CanL) has been documented since 1985. Notably, there has been a surge in CanL cases since 2017, with two autochthonous cases of human visceral leishmaniasis reported in the area in 2021. This study aimed to identify the sand fly fauna potentially involved in disease transmission. Modified Centers for Disease Control light traps were deployed in three neighborhoods of the city where CanL cases had been previously reported, spanning January 2021 to December 2022. Of the 89 collections conducted, 119 sand flies belonging to five species were captured: Pintomyia fischeri (76/119, 63.86%), Migonemyia migonei (23/119, 19.33%), Lutzomyia longipalpis (16/119, 13.45%), Brumptomyia sp. (2/119, 1.68%), and Psathyromyia lanei (2/119, 1.68%), predominantly between February and April in 2021 and 2022. Polymerase chain reaction testing on all female specimens yielded negative results for Leishmania spp. DNA. Although Leishmania spp. was not detected in these vectors, these findings underscore the imperative to implement measures aimed at curtailing the proliferation of these insects.
