What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
volume reduction rate	The volume reduction rate (VRR)was calculated by the equations: VRR=([initial volume-final volume] × 100)/initial volume	through study completion, an average of 6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
rate of complications	complications after ablation	1 week
cosmetic score	The cosmetic score was assessed by a physician (1, no palpable mass; 2, no cosmetic problem but palpable mass; 3, a cosmetic problem on swallowing only; and 4, a readily detected cosmetic problem)	through study completion, an average of 6 months
symptom score	The symptom score was self-measured by patients using a 10-cm visual analogue scale (grade 0-10)	through study completion, an average of 6 months
rate of nodule regrowth	Regrowth was defined as ≥50% volume increase compared to the previously recorded smallest volume during the follow-up	through study completion, an average of 6 months
rate of change of thyroid function	thyroid function test, including free triiodothyronine, free thyroxine, thyroid stimulating hormone, thyroid peroxidase antibody and anti-thyroglobulin antibodies	through study completion, an average of 6 months
rate of disappearance	complete disappearance of ablated nodule on ultrasound and contrast-enhanced ultrasound	through study completion, an average of 6 months
