The impact of nutritional interventions targeting infants and children in Sub-Saharan Africa: a systematic review and meta-analysis.
Synthesis in BMC nutrition, 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
backgroundMalnutrition among African children remains a critical public health issue, with high stunting, wasting, and underweight rates. Despite nutritional interventions, gaps persist in long-term effectiveness, scalability, and contextual adaptability. This review synthesizes evidence on the impact of nutritional interventions including both standalone nutrition education and integrated multi-component interventions targeting infants and children in Sub-Saharan Africa.
methodsThrough systematic searches in Scopus, PubMed, Cochrane Library, and additional sources, eligible randomized controlled trials evaluating behavioural change communication, infant and young child feeding practices, nutritional status, and associated health outcomes were identified. Two reviewers independently handled study screening, data extraction, and bias assessment with Cochrane RoB-2, resolving conflicts by consulting a third party. A total of 15 randomized controlled trials (13 high-quality, 2 medium-quality) were included. A random-effects model meta-analysis pooled odds ratios for three outcome categories: (1) infant and young child feeding practices, (2) behavioural change, and (3) nutritional status along with other health indicators. Heterogeneity was evaluated using the I
resultA review of 15 randomized controlled trials from 10 Sub-Saharan African countries (N = 12,613) revealed that both standalone and integrated nutrition interventions significantly improved infant and young child feeding (IYCF) practices (pooled OR = 1.997, 95% CI: 1.643-2.428, p < 0.001; I
conclusionIntegrated nutrition and behavior change interventions improve feeding practices, but not short-term child nutrition. Programs should combine education, food security, and community engagement, tailored to local contexts. Policymakers must prioritize multi-sectoral approaches to address malnutrition's root causes effectively. Systematic review PROSPERO registration number: CRD42025642826.
