Table 3A.
Multivariate model results with top 15 SNPs (ranked by p-value) associated with time to acute rejection, stratified by transplant center. Model also adjusted for recipient factors (race, age, gender, weight), PRA presence, number of HLA mismatches, T or B-cell cross-match positive, antibody induction, type of calcineurin inhibitor used, steroid use at day 14 post-transplant, simultaneous kidney-pancreas transplant (versus kidney transplant alone), cause of ESRD, living donor (versus deceased donor) and donor age. All variant data from dbSNP Build 131

Analysis conducted using a Cox proportional hazards model.
Same SNPs seen in the top 15 SNPs associated with cellular acute rejection.
There was some linkage disequilibrium (LD) between the two SNPs in CYP17A1, with r2= 1.00 in non-African Americans and African Americans, separately. There was also some LD between the two SNPs in ATR, with r2 >0.95 The remaining SNPs in the table had an r2 < 0.2.
