Effect of posterior tibial nerve stimulation on VAS, ICSI and ICPI scores

	Baseline	PTNS	% change from baseline	p value
VAS Mean ±SD Min–Max	6.1 ±1.6 (3–10)	4.6 ±0.9 (3–6)	24.6	<0.001
ICSI Mean ±SD Min.–Max.	13.8 ±4.1 (6–20)	5.9 ±2.4 (1–11)	57.2	<0.001
ICPI Mean ±SD Min.–Max.	11.7 ±4.1 (4–19)	6.5 ±2.1 (2–12)	44.4	<0.001

SD – standard deviation; VAS – visual analag scale; ICSI – Interstitial Cystitis Symptom Index; ICPI – Interstitial Cystitis Problem Index
