Anopheles species associated with malaria transmission in gold-mining areas of northwest Colombia.
Article in Malaria journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 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
backgroundIn Colombia, mining is one of the main economic activities in four eco-epidemiological areas that contributes approximately 80% of annual malaria cases. Mining activity generates changes in the environment and creates newly available breeding sites to be colonized by malaria vector mosquitoes, which increases the risk of malaria transmission. The study aimed to identify the presence of Anopheles species and their role in malaria transmission in five malaria-endemic localities with gold mining extraction in El Bagre, Antioquia, Colombia.
methodsA cross-sectional study was conducted in five localities of El Bagre, Antioquia where adult mosquitoes were collected indoors and outdoors. The taxonomic status of the Anopheles species was confirmed through COI sequencing. All mosquitoes were tested by ELISA to establish infection with Plasmodium spp., and infections were confirmed using nested PCR. Larval habitats were characterized to evaluate the association between Anopheles larval abundance and physical and biological parameters.
resultsEleven Anopheles species were identified. Six specimens were positive for PCR Plasmodium test: Anopheles darlingi infected with Plasmodium falciparum, Anopheles nuneztovari s.s., and Anopheles punctimacula infected with Plasmodium vivax. The entomological inoculation rate (EIR) varied across localities ranging from 1.5 to 6.6 infective bites/person/month. The Anopheles species were collected from natural and artificial man-made excavations for gold mining, nevertheless, the physical and biological parameters examined did not show a significant association with their abundance in either type of larval habitat.
conclusionsThe results confirm the role of An. darlingi, An. nuneztovari s.s. and An. punctimacula as malaria vectors. The presence of their immature stages in gold mining excavations identified these habitats as potential breeding sites for Anopheles species in El Bagre. In these areas, implementing larval source management might be recommended as a supplementary measure for LLINs and IRS in the malaria vector program.
