Socio-economic inequalities in malaria prevalence among under-five children in Ghana between 2016 and 2019: a decomposition analysis.
Review in Malaria journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundIn a country with limited and unequally distributed resources, and plagued with malaria annually, under-five children are severely affected by this disease in Ghana. While the epidemiological burden of malaria on under-five children is well-documented, the extent and contributors of socio-economic inequalities in malaria prevalence remain under-explored. This study examined the intertemporal socioeconomic status (SES)-related inequalities in malaria prevalence among under-five children in Ghana from 2016 to 2019 and identified the key factors contributing to these disparities.
methodsData were drawn from the 2016 and 2019 Ghana Malaria Indicator Surveys (GMIS). The study population consisted of under-five children who were tested for malaria in both surveys. Malaria prevalence served as the outcome variable, with the wealth index used as a proxy for socio-economic status. Socio-economic inequalities in malaria prevalence were evaluated using concentration indices and concentration curves. A decomposition analysis was employed to identify the socio-economic factors contributing to the observed inequalities.
resultsA total of 2323 children in 2016 and 1938 children in 2019 were tested for malaria. Malaria prevalence increased from 8% in 2016 to 10% in 2019. The concentration index for 2019 (Concentration Index = - 0.224; Standard Error = 0.059; p-value = 0.000) was statistically significant and negative, indicating higher malaria prevalence among children from lower socio-economic backgrounds. However, the concentration index for 2016 (Concentration Index = - 0.052; Standard Error = 0.044; p-value = 0.230) was not statistically significant. In 2019, socio-economic status, region, and ethnicity accounted for 59.38%, 23.66%, and 4.46%, respectively, of the observed inequalities in malaria prevalence.
conclusionThe study revealed a persistent pro-poor inequality in malaria prevalence in under-five children in Ghana, underscoring the importance of targeted malaria control interventions. These interventions should prioritize socioeconomically disadvantaged groups to reduce inequalities in malaria prevalence which contributes to the 2030 Sustainable Development Goals of improving health (SDG 3) and reducing inequalities (SDG 10), among others.
