Spatial and temporal inequalities in non-communicable disease mortality across the East African community: a Bayesian spatio-temporal analysis.
Article in Frontiers in public health, 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
Introduction: Non-communicable diseases (NCDs) are increasing rapidly across Sub-Saharan Africa, yet spatial inequalities in mortality across disease groups remain insufficiently characterized for effective regional health planning. Methods: We examined mortality from cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes across seven East African Community countries from 2000 to 2019. Using WHO Global Health Observatory estimates, we constructed a balanced panel of 560 country-disease-year observations and fitted a multivariate Bayesian spatio-temporal shared-component model in INLA with environmental and socioeconomic covariates. Results: Socioeconomic context showed the strongest associations with mortality risk. GDP per capita was positively associated with NCD mortality, while healthcare expenditure, urbanization rate, and population density showed inverse associations. Environmental variables were weaker and statistically uncertain at country scale. Spatial patterns showed elevated cardiovascular and respiratory mortality risk in eastern areas, a west-to-east gradient for diabetes, and relatively uniform cancer mortality. Shared spatial effects identified persistent multi-disease high-risk clustering centered on Rwanda, Uganda, and Tanzania. Discussion: NCD mortality risk in the EAC is spatially structured and associated with contextual socioeconomic and environmental conditions, underscoring the importance of geographically targeted prevention strategies and spatially informed health-system planning.
