SECONDARY outcome

Timeframe: 12 weeks

Population: The analysis population for this outcome is larger than the number of participants who completed the trial because a few participant answered this question without completing the other questionnaires

The response rate for the global response assessment was based on marked or moderate improvement at 12 weeks using a 7 point scale (marked worsening, moderate worsening, no change, slight improvement, moderate improvement, marked improvement).

SECONDARY outcome

Timeframe: Baseline and12 weeks

For the National Institutes of Health Chronic Prostatitis Symptom Index (NIHCPSI), higher scores indicate more severe symptoms (for the quality-of-life score, higher scores indicate a more negative effect). Score ranges are as follows: total score, 0 to 43; pain score, 0 to 21; urinary score, 0 to 10, quality-of-life score, 0 to 12; and average pain and urgency scores, 0 to 10.
