Methods
A total of 480 consecutive patients for ischemic stroke within 48 hours
of onset were retrospectively enrolled in this study. Thyroid hormones
including thyroid-stimulating hormone (TSH), free triiodothyronine
(FT3), and free thyroxine (FT4) were measured at admission and
functional outcomes were assessed at 3 months with the modified Rankin
Scale (mRS) ranging from 0 to 6. Poor outcome was defined as mRS≥3.
