Effectiveness of nutritional education intervention during pregnancy on birth outcomes in sub-Saharan Africa: a protocol for a systematic review and meta-analysis.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionNutritional education intervention during pregnancy is the process of teaching pregnant women about the importance of a healthy diet and how to make healthy food choices. It is an important part of public health and vital to preventing adverse birth outcomes. Therefore, synthesising available evidence on the effect of nutritional education intervention on birth outcomes is essential for decision-making by policymakers and for identifying needed gaps for future research.
objectiveTo systematically collect, review and summarise available evidence on the pooled effect of the nutrition education to pregnant women on birth outcomes in sub-Saharan Africa. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measures will be birth outcomes, while maternal outcomes will be treated as secondary. METHODS AND ANALYSIS: This systematic review will systematically search and collect data from a variety of databases, including the MEDLINE, CINAHL, EMBASE, Joanna Briggs Institute Database, Cochrane Database, PEDro, POPLINE, ProQuest, OpenGrey (SIGLE), Google Scholar, Google, APA PsycINFO, Web of Science, Scopus and HINARI. In addition, the systematic review will also search for unpublished studies and grey literature from a variety of sources. The review will only include experimental and quasi-experimental studies published in English from 1 January 2013 to 31 December 2023. Two independent reviewers will critically appraise all eligible studies for methodological quality using the standard Joanna Briggs Institute (JBI) Critical Appraisal Checklist for randomised controlled trials. Any disagreements between the reviewers will resolve through discussion. Either a random effects or fixed effects model will be used to pool the data, depending on the appropriateness of the model. The heterogeneity will be assessed statistically using the standard χ² and I ETHICS AND DISSEMINATION: By synthesising existing research without ethical concerns, this impactful review will be published and presented across academic and relevant institutions. PROSPERO REGISTRATION NUMBER: CRD42023473371.
