Inequalities in diarrhoea, pneumonia and measles deaths: estimates for 21 sub-Saharan African countries.
Article in Bulletin of the World Health Organization, 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
Objective: To develop new methods to analyse the distributions of diarrhoea, pneumonia and measles deaths in children younger than 5 years across wealth quintiles. Methods: We used Demographic and Health Surveys conducted since 2013 from 21 sub-Saharan African countries. We implemented multidimensional optimization techniques to estimate the joint impact of risk factors (that is, stunting, wasting, underweight, vitamin A deficiency and unsafe sanitation), immunization coverage and treatment utilization, on the distribution of deaths from diarrhoea, pneumonia and measles across wealth quintiles in each country. For each country, we created wealth-related gradients to show the risk of dying from either diarrhoea, pneumonia or measles. Findings: Across all countries and diseases, the risks of dying from diarrhoea, pneumonia and measles decrease with increasing household wealth: children in the wealthiest quintile are at the lowest risk (set to 1), except in a few rare instances. Yet, the magnitudes of these estimated risk gradients varied considerably across diseases and countries, from under 2 to above 10. Wealth-related risks of dying seemed to be unrelated to the countries' levels of under-5 mortality. Conclusion: We estimate that inequalities in deaths from diarrhoea, pneumonia and measles are large in many countries of sub-Saharan Africa, with more deaths occurring among children in the poorest wealth quintiles compared with the richest. Our new and generalizable methods can help research on health disparities to explore new directions.
