Table 3:

Risk factors for any acute rejection event in the first year post-transplant identified using multivariable logistic regression.

Parameter	P-value	Odds Ratio	95% Wald Confidence Limit
Age at Transplant (years)*	0.0117	1.066	(1.014, 1.121)
Race (Non-black vs. black)	0.0043	3.181	(1.239, 8.166)
(Unknown vs. black)	0.4145	1.160	(0.331, 4.071)
Sensitization (non-DSA ab vs. no ab)	0.0527	1.923	(0.992, 3.725)

Note: Variables were selected using backwards elimination with α=0.10 threshold for inclusion Potential variables included age, gender, race, ethnicity, diagnosis of congenital heart disease, ABO incompatibility, UNOS status at transplant, history of prior sensitizing event, and presence of non - DSA antibodies.

^*Odds ratio represents the increase in odds for a one year increase in age.
