title: Correction: History and Future of Treatment of Hypothyroidism.
abstract: There is an error in a recent article. The last sentence of the section titled "L-Thyroxine Monotherapy Fails to Restore All Markers of Hypothyroidism" should read "new technology is needed to allow for steady delivery of L-triiodothyronine" (it currently reads "… for steady delivery of L-thyroxine").This has been corrected in the online version.
