1 · What the graph read from it

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.

2 · The registry

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

purposeThe rising incidences of insecticide resistance in mosquito vectors highlight the need for continuous monitoring of their susceptibility to chemical insecticides. Therefore, this study assessed the susceptibility status of the Aedes aegypti mosquitoes against the chemical insecticide Temephos. At the same time, there is a growing global interest in increasing the use of bio-larvicides in vector management programs. In this context, it is important to evaluate the effectiveness of bio-larvicides, such as Bacillus thuringiensis israelensis (Bti) toxins, in comparison to conventional chemical insecticides.

methodsTo evaluate the susceptibility of Aedes aegypti larvae to chemical and biological larvicides, mosquitoes were collected from various breeding sites within the study area. First-generation (F

resultsAt the WHO-recommended diagnostic concentration of 0.02 ppm of Temephos, Aedes aegypti larvae exhibited a mortality rate of 50.33%, indicating confirmed resistance. The calculated LC

conclusionThe study underscores a significant decline in Aedes aegypti susceptibility to the chemical larvicide Temephos, posing challenges for vector control programs. In contrast, Bti showed substantial efficacy, suggesting its potential as a viable, eco-friendly alternative. Increasing the Bti share in comprehensive vector management strategies could enhance control measures against mosquito-borne diseases.
