Impact of kidney transplantation on the hazard rate of death caused by infection (n = 175; 16 deaths: 2 pretransplant and 14 post-transplant)

Predictor Variables in the Modela	Cox Model (Coefficient ± SE)	Wald Test (P)	Adjusted Relative Risk [95% Confidence Interval]
Post-Tx effect during 0 to 6 monthsb	3.281 ± 0.852	0.0001	26.62 [5.01 to 141.3]
Post-Tx effect >6 monthsb	0.524 ± 0.861	0.54	1.69 [0.31 to 9.14]
Listed for kidney/pancreas Txc	1.116 ± 0.607	00.07	3.05 [0.93 to 10.02]

Tx, transplant.

^aTwo distinct post-transplant effect time periods, adjusting for the single significant baseline covariate. Among the 14 post-transplant infection deaths, the numbers occurring during 0 to 6 and >6 months after transplantation were 7 and 7, respectively.

^bLikelihood ratio test (with 1 df) for equality of the post-transplant effects during 0 to 6 and >6 months after transplant yielded P < 0.001.

^cAll patients listed for a kidney-pancreas transplant were type 1 diabetics.
