(A) Rates of volumetric reduction success (endpoint: ≥ 50%) at 1-, 3- and 6-month follow-ups, expressed as numbers and rates; (B) rates of volumetric reduction success (endpoint: ≥ 7 mL) at 1-, 3- and 6-month follow-ups, expressed as numbers and rates.

	ATN (n = 18)	FTN (n = 18)	p value
A	Success rate (endpoint: ≥ 50%)
1 month	6/18 (33.3%)	3/18 (16.7%)	0.44
3 months	10/18 (55.6%)	12/18 (66.7%)	0.73
6 months	11/18 (61.1%)	16/18 (88.9%)	0.12
B	Success rate (endpoint: ≥ 7 mL)
1 month	6/18 (33.3%)	7/18 (38.9%)	0.72
3 months	13/18 (72.2%)	14/18 (77.8%)	0.70
6 months	13/18 (72.2%)	15/18 (83.3%)	0.42

p values were derived from Fisher’s exact test
