The donor race model is a univariable model and adjusted for donor race alone. Donor ADI is a univariable model and adjusted for donor ADI alone. Donor race and ADI model is a multivariable variable and adjusted for both donor race and ADI. Recipient race model is a univariable model and adjusted for recipient race alone. Recipient ADI is a univariable model and adjusted for recipient ADI alone. Recipient race and ADI model is a multivariable model and adjusted for both recipient race and ADI. Attenuation of the hazard ratio indicates potential confounding.
