Evidence Map

What The Sources Report

• Overall, iodine deficiency in the mother during pregnancy can have adverse effects on the health of both the mother and the fetus: for the pregnant woman, it can significantly increase the risk of hypothyroidism and goiter; for the offspring, iodine deficiency not only hinders fetal growth and development but may also impair the level of infant intellectual development. [Lv Yingying (2026); evidence level 1]
• Studies have shown that long-term iodine supplementation may increase the risk of thyroid dysfunction during pregnancy for pregnant women. [Lv Yingying (2026); evidence level 1]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For iodine supplementation thyroid function meta-analysis, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
