Mapping mosquito diversity in Kenya correlating species distribution with malaria prevalence across varied climatic parameters.
Article in Malaria journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMalaria is a major public health problem, with over half of the world's population, primarily in sub-Saharan Africa, at risk. Climate change is already affecting the prevalence of malaria, in part by altering the distribution and density of mosquito vectors. This study assessed the relationship between climate variables and mosquito species distribution on malaria prevalence in Kenya from January 2019 to June 2021.
methodsData from 23 Kenyan counties were analyzed using mixed-effect regression, spatial analysis, correlation analysis, and the Least Absolute Shrinkage and Selection Operator (LASSO) to select variables.
resultsMalaria prevalence was highest in the Lake Endemic (19%), followed by the Coastal Endemic (5%), semi-arid seasonal (2%), and low-risk (0.9%) malaria epidemiologic zones in 2020. Mosquito species distribution varied, with distinct ecological preferences observed with Anopheles gambiae dominated coastal and semi-arid areas, while Anopheles funestus was highest in the highland and lake zones. Regression analysis indicated that a combination of environmental factors and public health interventions, including insecticide-treated nets (ITN) coverage, was an important predictor of malaria prevalence. However, the relationship between these factors and malaria prevalence varied across regions and time periods.
conclusionThis study provides insights into the spatial dynamics of mosquito species and their distribution in relation to malaria epidemiological zones in Kenya, thereby informing targeted control strategies.
