Change in IPSS and OAB-q SF scores were estimated by comparing symptom scores between baseline and 6 weeks. Mean change and 95% CIs are presented. Outcomes are inverted so that positive changes reflect symptom improvement. The PGI-I category ‘a little better’ reflects the MID for both questionnaires. None of the participants scored ‘much worsened’ or ‘very much worsened’ on the PGI-I.
IPSS, International Prostate Symptom Score; MID, minimal important difference; OAB-q SF, Overactive Bladder Questionnaire short form; PGI-I, Patient Global Impression of Improvement.
