Table 5. Multivariate Cox Proportional Hazards Models for the Effect of Black Race on Graft Failure and Mortality With Adjustments for Clinical and Demographic Characteristics.

	Black: White [HR (95% CI)]	P Value
Models for graft failure
Crude model: race/ethnicity alone	2.62 (1.34-5.13)	0.0048
Race/ethnicity adjusted for clinical/demographic factors: race/ethnicity+-age at transplant+graft type	2.53 (1.29-4.96)	0.0136
Fully adjusted model: race/ethnicity+age at transplant+graft type-+insurance type+NDI	2.59 (1.29-5.45)	0.0407
Models for mortality
Crude model: race/ethnicity alone	5.05 (2.00-12.73)	0.0006
Race/ethnicity adjusted for clinical/demographic factors: race/ethnicity+-age at transplant+medical condition at wait listing	4.84 (1.91-12.26)	0.0043
Fully adjusted model: race/ethnicity+age at transplant+medical condition at wait listing+insurance type+NDI	4.24 (1.54-11.69)	0.0296

NOTE: P Values in bold are statistically significant (P<0.05).
