Mapping Malaria Susceptibility in the Oti Region of Ghana Using Remote Sensing and GIS: A Retrospective Observational Study.
Article in Health science reports, 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
Background: Malaria remains a major public health challenge in Ghana, with the entire population at risk of infection. Although the national prevalence has declined in recent years, malaria continues to cause significant morbidity and mortality. Aim: This retrospective observational study aimed to map malaria risk zones in the Oti Region using environmental factors. Methods: Malaria incidence and hotspots were analyzed using the Getis-Ord Gi* statistic in Esri ArcMap. Environmental factors influencing Results: Malaria cases were unevenly distributed across the Oti Region, with Krachi East and Nkwanta South identified as persistent hotspots for malaria. These regions reported 91,376 and 73,592 cases, respectively, over 3 years. Furthermore, elevation (with feature importance, 27.60%), land surface temperature (LST) (from 22°C to 32°C) (25.48%), normalized difference vegetation index (NDVI) (23.12%), and distance to rivers (20.00%) were the significant environmental factors affecting mosquito breeding and, consequently, malaria susceptibility within the study area. Conclusion: These findings provide valuable insights for guiding targeted control efforts and resource allocation in the Oti Region, focusing on addressing the identified environmental risk factors to mitigate malaria transmission in the area.
