Diagnostic value of urinary ATP in IC/BPS patients. (A) Comparison of urinary ATP concentrations between IC/BPS patients and asymptomatic controls. There is a significant difference between the two groups (P < 0.0001). (B) ROC curve for urinary ATP concentration. The AUC value for ATP was 0.828, indicating significance (P < 0.0001). ATP: Adenosine triphosphate; IC/BPS: Interstitial cystitis/bladder pain syndrome; Ctrl: Control; ROC: Receiver operating characteristic; AUC: Area under the curve.
