Figure 4 Kaplan-Meier survival curves of 3-year mortality in relation to thyroid function status. patients were classified into 5 categories according to their thyroid function status at admission: euthyroid (0.27≤ TSH ≤4.20 mIU/L), hypothyroidism or subclinical hypothyroidism (TSH >4.20 mIU/L with low FT3/FT4 levels or normal FT3/FT4 levels, respectively), hyperthyroidism or subclinical hyperthyroidism (TSH <0.27m IU/L with high FT3/FT4 levels or normal FT3/FT4 levels respectively). * Four patients were excluded: 2 with plasma TSH <0.27 mIU/L, low FT3 and normal FT4; and 2 with plasma TSH >4.20 mIU/L, high FT4 and normal FT3. TSH – thyroid-stimulating hormone; FT3 – free triiodothyronine; FT4 – free thyroxine.
