LT modality	MFS		OS
	HR (95% CI)	P value	HR (95% CI)	P value
Prior RP vs no prior LT	1.02 (0.67-1.53)	.94	0.71 (0.46-1.08)	.10
Prior RP plus RT vs no prior LT	1.13 (0.81-1.58)	.48	0.80 (0.57-1.13)	.21
Prior RT vs no prior LT	1.29 (0.95-1.73)	.10	1.18 (0.88-1.56)	.27

Abbreviations: HR, hazard ratio; LT, local therapy; MFS, metastasis-free survival; OS, overall survival; RP, radical prostatectomy; RT, radiation therapy.
