Multivariable Cox proportional hazard model for posttransplant mortality in simultaneous liver-kidney transplant recipients by liver-donor risk index (L-DRI) categories, after the propensity score matching

N = 1341	Hazard ratioa	95% confidence interval	P value
L-DRI (reference L-DRI < 1)
1–1.5	1.07	0.81–1.42	0.64
1.5–2	2.00	1.44–2.79	<0.001
>2	3.75	2.03–6.93	<0.001

^aAdjusted for the recipient factors (age, body mass index, race, gender, diabetes), waiting time, the cause of liver disease, blood type, model for end-stage liver disease at transplant encephalopathy at transplant, ascites on at transplant, mechanical ventilation/ICU stay and transplant year, and transplant type.
