First detection and entomological characterisation of invasive malaria vector Anopheles stephensi in sympatry with other vectors in Gayi Southern Niger Republic.

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
Anopheles stephensi, an invasive vector is aggressively expanding its geographic range across Africa, posing significant threat to malaria control. Surveillance of its spread is crucial for mitigating its impact on malaria transmission. Here, we report for the first time incursion of An. stephensi into Gayi, a rural area in southern Niger Republic. A combination of morphological identification, end point PCR and sequencing of fragments of COXI and ITS2 genes confirmed An. stephensi. This species was found resting indoor together with other mosquitoes, including An. coluzzii, An. gambiae s.s., and An. arabiensis. Entomological parameters, including resting densities, human blood index and biting rate, Plasmodium falciparum parasite rate, and entomological inoculation rate were described for the above Anopheles species. The finding of An. stephensi sympatric with the above major malaria vectors in Niger highlights the urgent need for intensified surveillance to develop evidence-based approaches to prevent further spread of this pervasive vector.
