A systematic review and meta-analysis of the association of dietary diversity with undernutrition in school-aged children.
Synthesis in BMC pediatrics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled it.
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
backgroundMalnutrition in childhood has lasting consequences; its effects not only last a lifetime but are also passed down from generation to generation such as short stature, school-aged children are the most vulnerable section of the population and require special attention, including nutrition.
methodWe searched Medline through PubMed, Scopus, and Web of Science to identify all observational studies published before Jun 2022. Observational studies with a pediatric population aged 5-18 years that evaluated risk estimate with 95% confidence intervals the relationship between dietary diversity and undernutrition (wasting, stunting, and thinness) were included. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) were followed.
resultsThis is a first systematic review and meta-analysis with a total of 20 studies were eligible (n = 18 388). Fourteen data evaluated stunting resulting in a pooled effect size estimated odds ratio of 1.43 (95% CI: 1.08-1.89; p = 0.013). Ten data evaluated Thinness resulting in a pooled effect size estimated odds ratio of 1.10 (95% CI: 0.81-1.49; P = 0.542). Two studies were revealed wasting with a odds ratio of 2.18 (95% CI: 1.41-3.36; p-value < 0.001).
conclusionAccording to the conclusions of this meta-analysis of cross-sectional studies, inadequate dietary diversity increases the risk of undernutrition in growth linear but not in thinness in school-aged children. The findings of this analysis suggest that initiatives that support improvements to the diversity of children's diets to reduce the risk of undernutrition may be warranted in LMICs.
