Error in units of measure. The article “Thyroid Disease in Pregnancy” (February 15, 2014, p. 273) contained errors in the units of measure for thyroid-stimulating hormone, thyroxine-binding globulin, and free triiodothyronine in Table 2 (p. 274). The unit of measure for thyroid-stimulating hormone should be mIU per L (rather than mIU per mL); for thyroxine-binding globulin should be mg per dL (rather than mcg per dL); and for free triiodothyronine should be pg per mL (rather than pg per dL). The online version of this article has been corrected.
