Effect of Zinc supplementation on child development: a systematic review and metaanalysis Protocol.
Review in Iranian journal of child neurology, 2021. 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
Child development is one of the principal aspects of pediatrics. It is a multidimensional process, on which many factors may have different effects. Zinc is a nutritional trace element that has an essential role in neuronal activity and, consequently, in brain development. Since Zinc deficiency is prevalent in developing countries, some clinical trials were conducted to evaluate the impact of zinc supplementation on child development. Thus, we decided to run a systematic review in this area to identify the effectiveness of zinc supplements on child development. This systematic review protocol will include randomized controlled trials studies (RCTs) in which zinc supplementation was used versus placebo or no intervention, zinc supplementation with other micronutrients versus the same micronutrients without zinc. We will evaluate the effect of zinc alone and zinc co-supplementation with iron on child development. We will search the Medline, Pubmed, EMBASE, ERIC, Psychinfo, the Cochrane Central Register of Controlled Trials (CENTRAL), clinicaltrials.gov, WHO International Clinical Trials Registry Platform (ICTRP), ISRCTN Registry CINAHL, Web of Science and Scopus databases. The clinicaltrials.gov and the Cochrane Library website will also be searched for randomized trials which were registered and completed but not published yet. Two researchers will independently screen titles and abstracts of citations and read the full texts of potentially relevant studies. The data extraction and quality assessment of the papers will be done independently. Any disagreements that arise between the reviewers in the above-mentioned steps will be resolved through discussion. We will report our findings based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and use the Cochrane Collaboration's tool for assessing the risk of bias. We will aim to synthesize the results in a meta-analysis if the interventions are similar in methods. Based on the similarities and differences of primary studies, we will use the best statistical methods. This is a protocol of systematic Review and meta-analysis of the effect of zinc supplementation on child development. The strengths of this protocol after meta-analysis are as follows
