Geospatial Mapping of People Living With Diabetes and Hypertension in Urban Slums of Central Karnataka, India.
Article in Cureus, 2025. 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
backgroundDiabetes mellitus and hypertension continue to rise in India, particularly among socioeconomically disadvantaged urban slum populations. This study presents a geographic information system (GIS)-based approach to mapping the geospatial distribution and sociodemographic profile of affected individuals.
objectivesTo determine the geospatial distribution and sociodemographic characteristics of individuals living with diabetes mellitus and hypertension in urban slums of central Karnataka, India. METHODOLOGY: A community-based cross-sectional survey was conducted in the field practice areas of the Urban Health Training Centre, Jagadguru Jayadeva Murugarajendra (JJM) Medical College, Davangere, in central Karnataka, from November 2024 to April 2025. Data were collected via house-to-house visits using structured questionnaires programmed on Android phones via Epicollect5 (Centre for Genomic Pathogen Surveillance, Big Data Institute, University of Oxford, Oxford, UK). Geotagging of residences was done, and GIS mapping was created using QGIS software (QGIS Development Team, Open Source Geospatial Foundation, Beaverton, OR).
resultsAmong 576 individuals, 112 (19.4%) had diabetes, 174 (30.3%) had hypertension, and 290 (50.3%) had both. The majority (192, 33.3%) were elderly, with a mean age of 58 ± 6.12 years. Females comprised 55.9% (322), and most participants (187, 32.4%) had formal education up to 10th grade. A total of 345 (59.9%) belonged to the low socioeconomic class, as per the modified BG Prasad classification (updated for January 2025). Clustering was observed in specific slums.
conclusionGIS-based mapping enables the identification of areas with a high burden of disease, facilitating targeted public health interventions in underserved urban slum settings.
