The effectiveness of education-based interventions on iodine knowledge, attitude, behaviour, and status: a systematic review protocol.
Article in Systematic reviews, 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
backgroundIodine deficiency remains a significant public health issue, further highlighted by the concern of its re-emergence in multiple countries. The health burden of iodine deficiency is high, especially in those who are vulnerable to the effects of iodine deficiency, such as pregnant women, infants, and children. Studies have shown that the public has low awareness and misconceptions regarding iodine. Increasing the understanding of the importance of iodine and its sources are crucial steps in controlling iodine deficiency in populations. This proposed systematic review aims to evaluate the effectiveness of education-based interventions and identify effective strategies that are associated with improved iodine knowledge, attitude, behaviour, and/or status, which could assist in improving iodine intake and combatting iodine deficiency.
methodsThis protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) 2015 guidelines. The electronic databases that will be used to search for relevant studies are PubMed/MEDLINE, Web of Science, ScienceDirect, Scopus, and EMBASE, with no restriction on population and date. We will also explore Google Scholar to identify relevant studies. Two reviewers will perform the screening and data extraction, and disagreements will be solved by discussion or a third reviewer. We will synthesise the findings using meta-analyses where possible or otherwise via a narrative synthesis. DISCUSSION: The findings of the review will help to inform and guide the development and implementation of education programmes and evidence-based health interventions aimed at preventing iodine deficiency, with potential applicability to wider public health strategies. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42025065136.
