Table 2. Volume reduction rate (VRR) and therapeutic success rate (TSR)

Volume (Mean ± SD), ml	Number of patients (n)	Value	p
Baseline	17	5.21 ± 3.37	<0,05
1-month post-treatment	17	2.35 ± 2.52
VRR (%)*	17	52.87
	≥50%	9	52.90
	< 50%	8	47.1

Therapeutic success rate (TSR) defines as volume reduction rate (VRR) ≥50%;
: statistically significant reduction (p-value<0.05).
