Radioactive iodine effects on ovarian reserve: a systematic review and metaanalysis.
Synthesis in Frontiers in endocrinology, 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
Background: Differentiated thyroid carcinoma (DTC) is common, and its rate is on the rise globally. Radioactive iodine, RAI (I-131), is widely used as an adjuvant therapy or for remnant ablation. There is growing awareness about the effects of RAI (I-131) on ovarian reserve. Materials and methods: This meta-analysis aimed to evaluate whether RAI therapy impairs ovarian reserve as assessed by anti-Müllerian hormone (AMH) and follicle-stimulating hormone (FSH) levels. A systematic literature search was conducted in PubMed, MEDLINE, Google Scholar, and EBSCO for relevant articles published in the English language. The literature search was conducted during October and November 2024, and the studies were included if they were published in the period from 2015 to 2024. The keywords used were ovarian reserve, ovarian function, female fertility, radioactive iodine, RAI (I-131), follicle-stimulating hormone (FSH), and anti-Müllerian hormone (AMH). MeSH terms used: Iodine Radioisotopes, Ovarian Reserve, and Thyroid Neoplasms. Result: Out of the two hundred and sixty-nine studies retrieved, 160 remained after duplication removal, of which 17 full texts were screened. However, only six studies (with 430 patients) were included in the final meta-analysis. AMH level were significantly lower after RAI (I-131) with a mean difference (MD) of 1.96. 95% Conclusion: Current evidence shows a significant reduction in anti-Müllerian hormone (AMH), and significant increase in FSH levels after RAI (I-131), but data are heterogeneous. Larger prospective studies with standardized outcome measures are needed.
