Determinants of malnutrition among children under 5 years in refugee and internally displaced person populations: a protocol for systematic review and meta-analysis.
Article in BMJ open, 2025. 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
introductionMalnutrition is a critical global health issue, particularly among the vulnerable children whose socioeconomic, sociocultural and environmental characteristics are unique. Malnutrition significantly increases the risk of mortality and non-communicable diseases, impairs physical growth, hinders cognitive development and limits children's potential. While a number of earlier studies explored the determinants of malnutrition among children under 5 years of age in refugee and internally displaced person (IDP) populations, comprehensive reviews are scarce. A systematic synthesis of existing data is essential to better understand its prevalence and associated risk factors, informing more effective interventions. METHOD AND ANALYSIS: This systematic review protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We will conduct a comprehensive search in PubMed, Scopus and ProQuest. Additionally, relevant grey literature will be explored using Google Scholar and Google Advanced Search. We will include cross-sectional, cohort and case-control studies published in English that report the prevalence of malnutrition and associated factors among children under 5 years of age in refugee and/or IDP populations. Two reviewers will screen and extract data independently. The quality of the included studies will be assessed using the Joanna Briggs Institute critical appraisal tool. Meta-analysis will estimate pooled prevalence of malnutrition, as well as the pooled OR for associated factors, using a random-effects model with 95% CIs. Heterogeneity will be assessed using the χ² test and I² value. ETHICS AND DISSEMINATION: Ethical approval is not required. The results will be published in a peer-review journal and presented at conferences. PROSPERO REGISTRATION NUMBER: CRD42024611728.
