Patient Allocation.

<p>Of 429 patients who underwent liver transplantation at our institution from December 2006 till March 2011, 266 were eligible for inclusion in the study. ^*incl. 18 HU-listed, 33 split/living related, and 5 retransplantations; excl. ^**<18 years; ^***<18 years or HU-listed; ^****<18 years, HU-listed or split/living related or combined organ transplantation.</p

Multivariate, logistic regression analysis of patient survival rates.

<p>Final model of the multivariate logistic regression analysis of clinical parameters associated with the 90-day timeframe for patient survival in the study population. Clinical parameters included in the multivariate analysis were significant at the 10% level in the univariate analysis. OR: odds ratio; CI: confidence interval; DRI: donor risk index.</p
