Mean thyroid hormone levels from pre-radiotherapy to 48 months after radiotherapy.
The error bars represent the standard deviation (SD) of the hormone levels at the specific time interval. fT3: Free triiodothyronine, fT4: Free thyroxine, TSH: Thyroid-stimulating hormone, 0m = pre-radiotherapy, m = month.
