Iodine supplementation corrects thyroid dysfunction

No statistics for this claim: This paper performs a meta-analysis only for children's cognitive outcomes — there is no statistical analysis testing whether iodine supplementation corrects thyroid dysfunction

Narrative summary only for thyroid indices: While some individual trials within the review do report significant improvements in thyroid markers like thyroglobulin and TSH, these are individual trial results and were never pooled statistically.

What the paper actually shows: Iodine supplementation improved some thyroid indices in some individual trials, but this is not the same as correcting thyroid dysfunction, and no pooled statistical evidence supports this specific claim

Bottom line: Because there is no quantitative analysis — neither pooled nor specifically targeting dysfunction correction — this paper cannot be used as statistical evidence that iodine supplementation corrects thyroid dysfunction.
