Log iPSA(ng/mL)		2.02	1.60–2.52	<0.001
Age(years)		1.00	0.98–1.02	0.992

Comorbidities(yes vs no)
Diabetes		1.09	0.71–1.69	0.691

BF, biochemical failure; BMI, body mass index; HR, hazard ratio; ADT, androgen deprivation therapy; iPSA, pre-treatment prostate specific antigen.

^*Hazard ratios are from a single stratified Cox proportional hazards model, adjusted for T-stage and Gleason score as stratification variables.
