Text: Compared with morning intake, direct treatment effects when levothyroxine was taken at bedtime were a decrease in thyrotropin level of 1. 25 mIU/L (95 % confidence interval [CI], 0. 60-1. 89 mIU/L ; P <. 001), an increase in free thyroxine level of 0. 07 ng/dL (0. 02-0. 13 ng/dL ; P =. 01), and an increase in total triiodothyronine level of 6. 5 ng/dL (0. 9-12. 1 ng/dL ; P =. 02) (to convert thyrotropin level to micrograms per liter, multiply by 1. 0 ; free thyroxine level to picomoles per liter, multiply by 12. 871 ; and total triiodothyronine level to nanomoles per liter, multiply by 0. 0154).
