Linear regression analysis of urinary ATP concentration and IC/BPS symptom scores in IC/BPS patients. Urinary ATP of IC/BPS patients showed a significant positive correlation with (A) VAS (r ═ 0.6070; P < 0.0001), (B) ICSI (r ═ 0.5822; P < 0.0001), and (C) ICPI (r ═ 0.5234; P < 0.0001). ATP: Adenosine triphosphate; IC/BPS: Interstitial cystitis/bladder pain syndrome; VAS: Visual analog score; ICSI: Interstitial cystitis symptom index; ICPI: Interstitial cystitis problem index.
