Nutritional Status of Iodine and Association with Iron, Selenium, and Zinc in Population Studies: A Systematic Review and Meta-Analysis.
Synthesis in Nutrients, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Micronutrient deficiencies are not always present in individuals independently and may occur in association with other deficiency processes.
objectiveVerify the association between the nutritional status of iodine and that of iron, selenium, and zinc in population studies.
methodsA bibliographic search was carried out in Medline, Web of Science, and CINAHL databases, without date and language restrictions, using English search terms and their synonyms. The search terms were joined by the Boolean operator AND while the respective synonyms were connected by OR following the PRISMA guidelines.
resultsA total of 40 articles were included. The studies were published between 1993 and 2025, mostly involving both sexes and the main age groups were children and adolescents. Among the micronutrients analyzed, selenium stood out, being evaluated in 55.0% (
conclusionsThe coexistence of deficiency processes in an individual still needs to be further elucidated. Combined strategies that effectively combat, prevent, and treat these micronutrient deficiencies must consider the possible interactions between them.
