In the above-named article by Petersen M, Knudsen N, Carlé A, Andersen S, Jørgensen T, Perrild H, Ovesen L, Rasmussen LB, Thuesen BH, and Pedersen IB (J Clin Endocrinol Metab. 2019;104(5):1833–1840; doi: 10.1210/jc.2018-01993), the following error occurred during the production process of the accepted manuscript: two instances of the word “iodine” were replaced with “iron” in the introduction section of the article.

The correct text is “Iodine deficiency (ID) is one of the most common types of specific nutritional deficiencies globally. Endemic goiter is common in severe iodine-deficient areas.”
