Multivariate^* Cox Proportional Hazards Regression of One-Year Graft Failure in LDLT Recipients stratified by preceding transplant volume (N=2566)

Covariate	HR (95% CI)	p-value
Transplant volume^ (ref: 0-5 group):**
6-15	0.69 (0.47-1.02)	0.063
16-25	0.62 (0.42-0.92)	0.018
26-40	0.61 (0.41-0.94)	0.024
>40	0.36 (0.21-0.62)	<0.001

HR = hazards ratio; CI = confidence interval; LDLT = living-donor liver transplant.

adjusted for donor age, recipient age, gender diabetes and life support requirement, and includes individual transplant centers as a random effect (theta = 0.04, likelihood-ratio test of theta=0: p=0.073) in a shared frailty model.
