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.

Abstract
backgroundMild-to-moderate iodine deficiency remains a public health challenge, particularly in Europe and in areas where access to iodine-rich foods or iodised salt is limited. Adolescents are a key target group for interventions, as early awareness can reduce the risk of iodine deficiency during future pregnancies. The EUthyroid2 project aims to raise iodine awareness among adolescents (aged 13–17y) to improve their iodine awareness and possibly iodine intake and indirectly enhance the health of them and their future children.
methodsA multi-country intervention study will be conducted in educational settings across six countries (Bangladesh, Pakistan, Slovenia, Cyprus, Germany and the UK). Data on iodine awareness, dietary habits, and socioeconomic status will be collected at baseline (T1), 2–4 weeks post-intervention (T2), and 26–34 weeks post-intervention (T3). A convergent parallel mixed-methods design will be employed for process evaluation. The intervention includes three components: teaching modules, an iodine feedback tool, and an online learning platform. The core content includes an iodine feedback tool and a lecture on iodine-related knowledge and awareness, accompanied by student exercises. A total of 4,500 students will be recruited. DISCUSSION: The main outcome of the study is the change in participants’ awareness and knowledge of iodine from baseline (T1) to follow-up points (T2 and T3). The intervention is expected to effectively improved understanding of iodine’s importance for health and promoted positive behavioural intentions related to iodine intake, while also providing an opportunity to enhance iodine nutrition beyond the scope of the current trial. This study contributes to evidence on effective health promotion approaches aimed at addressing iodine deficiency. Expanding such awareness interventions could lead to lasting improvements in public health by reducing the prevalence of iodine deficiency disorders, particularly among adolescents and future generations.
