Change scores for the IPSS and OAB-q SF by PGI-I outcomes: subgroup analysis for GP prescriptions

PGI-I outcome	N (%)	IPSS	Missing	OAB-q SF	Missing
Very much better	4 (3.1)	18.0 (1.7 to 34.3)	1	30.8 (−0.9 to 62.4)	0
Much better	39 (30.2)	9.2 (7.0 to 11.5)	2	19.9 (14.8 to 24.9)	2
A little better	57 (44.2)	5.4 (4.0 to 6.7)	3	11.2 (7.0 to 15.4)	3
No change	27 (20.9)	3.1 (0.5 to 5.6)	0	3.3 (−3.4 to 9.9)	3
A little worse	2 (1.6)	−8.5 (−11.6.5 to 99.5)	0	−16.5 (−353.2 to 320.2)	0

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.
