Univariate analyses by thyroid function status. Kaplan-Meier curves relative to breast cancer (BC) outcome (median follow-up 96.7 months) according to thyroid function status. Euthyroid, free-thyroxine (FT4) 9.0–19.1 pmol/L and/or thyrotropin (TSH) 0.30–4.40 mIU/L; hyperthyroid, FT4 >19.1 pmol/L and/or TSH <0.3 mIU/L; hypothyroid, FT4 <9.0 pmol/L and/or TSH >4.40 mIU/L. HR, hazard ratio (HR <1 indicates a favourable BC outcome); 95% CI, 95% confidence interval. a Disease-free survival. b Overall survival. c Time to recurrence.
