Beyond the battlefield: how conflict type drives acute child malnutrition in Africa.
Article in BMC public health, 2026. 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
backgroundContinuance of global progress toward the eradication of malnutrition in all forms requires the steering of resources to priority areas. Armed conflict is a key driver of malnutrition, yet its impact differs given the conflict intensity, duration and type. In this study, we investigate the relationship between conflict type, specifically state-based and non-state conflict, and under-5 acute malnutrition in conflict-affected African populations.
methodsWe link malnutrition data from small-scale surveys held in the Complex Emergency Database, conducted across 11 conflict-affected African populations between 1999 and 2015, with conflict data from UCDP/PRIO. We estimate associations between conflict type and the prevalence of global acute malnutrition (GAM) and severe acute malnutrition (SAM) whilst controlling for relevant covariates, using Bayesian beta-regression, which allows aggregation of survey data.
findingsHolding other factors constant, non-state conflict was significantly (p < 0.05) associated with a higher prevalence of GAM and SAM (15.27% and 4.83%) relative to state-based conflict (9.03% and 1.26%). In addition, we find heterogeneous impacts of prior military expenditure as a share of GDP, overseas development assistance (ODA) and precipitation variability on under-5 acute malnutrition by conflict type. Namely, prior military expenditure and lower-than-normal precipitation were associated with increased malnutrition prevalence under state-based conflict, yet to a lesser degree under non-state conflict. We find a significant mitigating role of ODA on GAM, irrespective of conflict type. For SAM, ODA was more negatively associated with malnutrition prevalence under non-state conflict relative to state-based conflict.
interpretationThe study extends the current literature by finding a heterogenous relationship between conflict type and under-5 acute malnutrition, namely we estimate a significantly higher malnutrition burden in African populations affected by non-state conflict relative to state-based conflict. Our findings underscore the importance of context-specific resource planning when addressing malnutrition burden in humanitarian crises.
