Triatoma chiarii sp. nov. (Hemiptera, Reduviidae, Triatominae): a new species in the Triatoma brasiliensis complex from Rio Grande do Norte state, Brazil.
Article in Parasites & vectors, 2025. 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
backgroundA new triatomine species was discovered in the semiarid Caatinga region of Rio Grande do Norte, Brazil, where it coexists with Triatoma brasiliensis in both natural and artificial habitats.
methodsTriatomine specimens were captured in peridomestic and sylvatic environments in Rio Grande do Norte. Their identification was based on a combination of analyses, including morphology using dichotomous keys, head and hemelytron morphometry, and phylogeny using cytochrome b and internal transcribed spacer markers.
resultsThe new species exhibits morphological traits that are intermediate between those of Triatoma brasiliensis and Triatoma petrocchiae, but has distinct characteristics, leading to its designation as Triatoma chiarii sp. nov. Geometric morphometric analysis of its wings and head clearly distinguished T. chiarii sp. nov. from T. brasiliensis and T. petrocchiae, while phylogenetic reconstruction confirmed its placement within the T. brasiliensis species complex. Both approaches consistently supported T. chiarii sp. nov. as a species closely related to T. petrocchiae, but with sufficient phenotypic and genotypic divergence to warrant its recognition as a new taxonomic entity.
conclusionsSince T. chiarii sp. nov. was also found in the peridomestic environment, its possible role in the eco-epidemiology of Chagas disease warrants further investigation.
