Cox Proportional hazards model for the covariates contributing to racial variations in overall survival of African Americans, Hispanics and Asians compared to Caucasians with local/regional prostate cancer

Variables in models	Hazard ratio (HR)and 95% Confidence Interval (CI) in African Americans, Hispanics and Asians compared to Caucasians*
	African Americans	Hispanics	Asians
	HR (95% CI)	HR (95% CI)	HR (95% CI)
Model 1: Race only	1.26 (1.21−1.32)	0.83 (0.75−0.92)	0.72 (0.66−0.79)
Model 2: Race + socio-demographics	1.13 (1.08−1.18)	0.82 (0.74−0.92)	0.66 (0.60−0.72)
Model 3: Race + socio-demographics + tumor characteristics	1.11 (1.06−1.16)	0.81 (0.73−0.90)	0.64 (0.58−0.70)
Model 4: Race + socio-demographics + tumor characteristics + ADT	1.12 (1.07−1.17)	0.81 (0.73− 0.90)	0.64 (0.58−0.70)
Model 5: Race + socio-demographics + tumor characteristics + ADT+ chemotherapy	1.12 (1.07−1.17)	0.81 (0.73− 0.90)	0.64 (0.58−0.70)
Model 6: Race + socio-demographics + tumor characteristics + ADT+ chemotherapy + primary therapies	1.06 (1.01−1.10)	0.79 (0.71−0.87)	0.64 (0.58−0.70)
Model 7: Race + socio-demographics + tumor characteristics + ADT+ chemotherapy + primary therapies + comorbidities	0.98 (0.94−1.03)	0.77 (0.69−0.86)	0.63 (0.58−0.69)
