Variables	Pre RFA	Post RFA*	P
Largest diameter (cm)	4.8 ± 0.3	3.1 ± 0.3	< 0.001‡
Volume (mL)	29.6 ± 6.3	12.0 ± 3.8	< 0.001§
Volume reduction rate		68.3 ± 4.4%
Therapeutic success†		90.5% (19/21)
Symptom score	5.4 ± 0.4	2.4 ± 0.3	< 0.001§
Cosmetic score	3.8± 0.1	8.6 ± 0.7	< 0.001§

Values are presented as mean ± standard deviation. ^*Entire data of post RFA was calculated at 12-month follow-up or 6-month follow-up when follow-up period was less than 12 months, ^†Therapeutic success (volume reduction > 50%) at 12-month follow-up or 6-month follow-up when follow-up period was less than 12 months, ^‡paired t test, ^§Wilcoxon signed rank test.
