Diagnostic criteria of the study.

No.	Diagnostic criteria
S1	Patients who had pelvic discomfort/pain for three or more months within the last six months; an overall score of 15 or greater of 43 points on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), including 1 or more on the pain subscale of this index or current pain.
S2	In accordance with European Association of Urology guidelines, patients with CPPS complained about pain perceived in structures related to the pelvis for at least three months without proven infection or other obvious pathology. Inclusion criteria were a NIH-CPSI total score of 15 or greater, NIH-CPSI pain subscale eight or greater.
S3	CP/CPPS patients had to report an unpleasant sensation of pain, pressure, or discomfort perceived to be related to the bladder and/or pelvic region for most of the time during the most recent three months.
S4	Patients had complaints about pelvic pain at least three months within the last six months; the NIH-CPSI total score was 15 or greater.
S5	In accordance with the European Association of Urology guidelines, all patients with chronic pelvic pain syndrome (CPPS) enrolled in this study reported pain perceived in structures related to the pelvis for at least three months without proven infection or other related pathologies.
S6	Meets National Institutes of Health diagnostic criteria for CP/CPPS.
S7	According to the category of National Institutes of Health, CP/CPPS was defined as urological pain or discomfort in the pelvic region sustained for no less than three months during the preceding six months that is associated with lower urinary symptoms and not in consort with a urinary tract bacterial infection.
S8	Based on the NIH-CPSI, patients with at least three months of persistent pelvic pain, urinary symptoms, and/or sexual dysfunction can make the diagnosis of CP/CPPS after excluding obvious etiologies such as active UTIs.
S9	The patient had pain and discomfort in the pelvic region for more than three months; NIH–CPSI score ≥15; normal white blood cell count and negative bacterial culture on routine prostate massage.
