	Patient group^a (n=25)			Control group (n=10)			P value^c
	Baseline	Posttreatment	P value^b	Baseline	Follow-up	P value^b	P value^c
Free T4	3.0±1.1	1.5±0.5	<0.001	1.4±0.1	1.4±0.1	NA	0.950
TSH	0.0 (0.0–0.0)	0.0 (0–0.4)	0.051	1.3 (1.1–2.3)	1.6 (1.0–3.2)	0.445	<0.001
K-HSS	12.0 (8.0–17.8)	4.0 (2.0–7.0)	<0.001	0.5 (0.0–2.8)	0.0 (0.0–2.0)	0.496	0.001

Values are expressed as mean±SD or median (interquartile range).

K-HSS, Korean version of the hyperthyroidism symptom scale; T4, thyroxine; TSH, thyroid stimulating hormone.

^aThose whose serum free T4 returned to reference range were analyzed (n=25); ^bBaseline vs. posttreatment/follow-up; ^cPosttreatment patient group vs. control group at follow-up.
