Age (reference age is ≤60 y)
60‐70 y	0.60	(0.18; 1.97)	NI
≥70 y	1.21	(0.46; 3.23)	NI
Baseline severity LUTS (IPSS)	0.93	(0.86; 1.00)	0.94	(0.87‐1.01)
BMI (reference point is ≤25)
25‐30	0.73	(0.30; 1.78)	NI
≥30	0.66	(0.18; 2.42)	NI
Lifestyle advice	1.10	(0.45; 2.70)	NI

Physical therapy	1.38	(0.55‐3.42)	NI

Note: The PGI‐I outcome scores were dichotomized into clear improvement (“much better” and “very much better”) and no clear improvement (all other PGI‐I scores).
