Spatiotemporal patterns of climate-sensitive vector-borne diseases in Bangladesh: leveraging machine learning and spatial regression for intervention strategies.
Article in BMC medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundBangladesh has a noticeable rise in vector-borne diseases (VBD) attributed to climate change. Accurately mapping, predicting, and identifying the risk factors of VBD is essential for prevention and control strategies. Therefore, this study aimed to investigate the spatiotemporal pattern and associated meteorological factors of VBD in Bangladesh.
methodsThis study used district-level reported cases of VBD (dengue, chikungunya, malaria, filariasis, and yellow fever) obtained from the Bangladesh Bureau of Statistics. Simultaneously, meteorological data (temperature, relative humidity, wind speed, and precipitation) were sourced from NASA from 2017 to 2020. A combination of exploratory spatial analysis, spatial regression, and advanced tree-based machine learning models was utilized for prediction, risk factor identification, and correlation analysis.
resultsDengue was the most prevalent vector-borne disease during the study period, peaking in 2019, while malaria and filariasis showed variable incidence across districts. Dhaka, Pirojpur, Jessore, Bandarban, Rangamati, and Narail districts exhibited higher incidence rates of VBD. The spatial regression model identified mean temperature as a major risk factor for VBD (β = 16.64, s.e. = 6.39). Additionally, the optimal XGBoost model also highlighted mean temperature as the primary determinant, alongside other climatic and socioeconomic factors such as GDP, population size, and healthcare infrastructure, underscoring the complex interplay between health infrastructure and socioeconomic drivers for Bangladesh's VBD from 2017 to 2020.
conclusionsThe study's findings, incorporating the One Health perspective, provide insights for planning early-warning, prevention, and control strategies using machine learning to combat infectious diseases in Bangladesh and similar endemic countries. Precautionary measures and intensified surveillance must be implemented in certain high-risk districts nationwide.
