Larvicidal effects of selected medicinal plant extracts against Anopheles arabiensis, Anopheles stephensi, and Aedes aegypti.
Article in Tropical medicine and health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe emergence of resistance to synthetic (chemical) insecticides along with their harmful effects on human health, non-target organisms and the environment necessitates the development of new complementary bioinsecticides that are effective, environmentally friendly, biodegradable and target-specific. This study was undertaken to evaluate larvicidal activities of 80% methanol and n-hexane extracts of four plants that are traditionally used by communities against mosquitoes.
methodsThe dried plant parts of Ocimum lamiifolium, Amaranthus hybridus, Premna schimperi, and Lepidium sativum were extracted with 80% methanol and n-hexane solvents. Bioinsecticidal activities of these extracts were evaluated under laboratory condition in the range of 62.5-2000 ppm against late 3rd to early 4th instar larvae of An. arabiensis, An. stephensi and Ae. aegypti mosquitoes. Larval mortality was observed after 24 h of exposure. The mortality data were subjected to probit analysis to determine LC

conclusionsThe n-hexane crude extracts of the tested plants have the potential to be used as bioinsecticides against larvae of An. arabiensis, An. stephensi and Ae. aegypti. Therefore, it is necessary to undertake studies that focus on bioassay-guided isolation, purification and structural elucidation of active compound (s) from the most active n-hexane fractions of the tested plants to develop a product that may complement the current existing vector control tools.
