Biochemical characteristics of patients with autoimmune hypothyroidism before and after 6 months of levothyroxine replacement therapy.

	Before Levothyroxine	After 6 Months of Levothyroxine	p Value
TSH (mIU/L)	19.8 (7.6–43.5)	1.8 (1.3–3.9)	0.002 *
FT4 (pg/mL)	0.16 (0.14–0.52)	1.01 (0.94–1.2)	0.01 *
Thyroid Peroxidase Antibodies (IU/mL)	82 (43–93)	78 (38–101)	0.35
Thyroglobulin antibodies (IU/mL)	25 (8.9–36.7)	20.7 (9.3–34.1)	0.15
FSS score	32 (15–48)	24 (16–32)	0.016

Quantitative variables were reported as median and interquartile range. BMI: body mass index; TSH: thyroid stimulating hormone; FT4: free thyroxine; FSS: fatigue severity scale. * p > 0.05 = statistical significance.
