Correction to: Thyroid 2017;27:315–389. DOI: 10.1089/thy.2016.0457

In the March 2017 issue of Thyroid (vol. 27, no.3; 315–389), the article entitled “2017 Guidelines of the American Thyroid Association for the Diagnosis and Management of Thyroid Disease During Pregnancy and the Postpartum” requires correction.

On page 347, Recommendation 47c should be corrected to read:

When shifting from MMI to PTU, a dose ratio of approximately 1:20 should be used (e.g., MMI 5mg/d = PTU 50 mg twice daily).

Strong recommendation, moderate-quality evidence.

The online version of the article has been corrected to reflect this change. The authors apologize for this error.
