Assessment of Undernutrition Among Under 5 Children in Developing Countries: A Systematic Review and Meta-Analysis.
Review in Health science reports, 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
Background and Aim: Undernutrition is gradually declining worldwide except in sub-Saharan Africa and parts of South Asia. Prevalence is almost stagnant in low-and middle-income countries (LIMCs), contributing to child mortality and disease burden. To systematically review existing literature and conduct a meta-analysis to estimate the prevalence of childhood undernutrition-specifically stunting, wasting, and underweight-and identify associated factors among children under five in developing countries. Methods: Following PRISMA 2020 guidelines, this study systematically reviewed literature from 2010 to 2022 across PubMed, Scopus, Cochrane Library and Web of Science on developing countries. Study quality was assessed using JBI scores. Meta-analyses estimated pooled prevalence and factors of undernutrition using the DerSimonian-Laird random-effects model. Heterogeneity was assessed via Results: We included 157 studies in this research. Pooled prevalence of stunting, wasting, and underweight was 33% (95% CI: 31-35), 12% (95% CI: 11-13), and 23% (95% CI: 21-25), respectively. Subgroup analysis indicates that Asia had the highest wasting (13%, 95% CI: 11-16) and underweight (27%, 95% CI: 23-31), while Africa had the highest stunting (35%, 95% CI: 33-38. Significant heterogeneity was found across studies and continents ( Conclusion: The findings underscore the need for targeted nutritional interventions addressing the identified socioeconomic and healthcare risk factors. Region-specific strategies will be essential to sustainably reduce undernutrition.
