Multivariate analysis of risk factors for prolonged delayed graft function (DGF)

	p-value
Donor age (years)	0.405
Donor plasma creatinine (μmol/L)	0.867
Donor eGFR (mL/min)	0.113
Expanded criteria donors	0.119
Cold ischemia time (hours)	0.416
Recipient age (years)	0.653
Mode of dialysis (hemodialysis or peritoneal dialysis)	0.861
Time on dialysis before transplantation (days)	0.867
Change in plasma creatinine from pretransplant to day 1	0.930
Recipient day 1 urine output (mL)	0.001
Recipient day 1 sNGAL (ng/mL)	0.042

eGFR = estimated glomerular filtration rate calculated using the MDRD equation, sNGAL = serum neutrophil gelatinase-associated lipocalin. Expanded criteria donor status defined according to Port et al. [28].
