Examining healthcare inequality for non-communicable diseases in Malawi: a hierarchical geospatial modelling approach.
Article in BMJ health & care informatics, 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
objectivesThe prevalence of non-communicable diseases (NCDs) is rising in low- and middle-income countries, including Malawi, yet spatial inequalities in NCD healthcare coverage remain poorly understood. In this research, we aim to: (1) develop a novel hierarchical geospatial framework to assess population coverage and accessibility of NCD services in Malawi and (2) identify underserved areas and provide evidence for targeted resource allocation.
methodsUsing 2019 Malawi Harmonized Health Facility Assessment Survey, hierarchical catchment areas were defined by facility type-primary healthcare (PHCs), district-level and central hospitals, with distance thresholds of 5 km walking, 25 km driving and 100 km driving, respectively. Incorporating facility readiness, we computed population coverage at the third administrative level. When estimating spatial accessibility, we used enhanced two-step floating catchment area, applying Gaussian distance decay for chronic conditions and inverse power for acute conditions.
resultsSecondary and tertiary facilities (STFs) covered over 60% of population, providing broader NCD service than PHCs, where coverage was lower than 20%, particularly for acute conditions. Population coverage was higher in central and southeastern Malawi, notably around Mzuzu, Lilongwe and Blantyre. However, at least 24% of the population were not covered for any NCD conditions. Additionally, only 11.9% of the population lived in regions of high or very high accessibility to PHCs. DISCUSSION: We found substantial geographic inequalities in NCD service coverage and access, highlighting underserved regions and the demand to strengthen PHC readiness.
conclusionThis hierarchical geospatial approach offers insights for resource allocation and improving healthcare equity in other low-resource settings.
