Patients characteristics and perioperative parameters by RIFLE classification.

The values are expressed as the median [interquartile range] or number (%). AKI = acute kidney injury; HBV = hepatitis B virus; HCV = hepatitis C virus; MELD score = model for end-stage liver disease score; CTP score = Child-Turcotte-Pugh score; GRWR = graft to recipient body weight ratio; GFR = glomerular filtration rate; pRBC = packed red blood cell; FFP = fresh frozen plasma; CNI = calcineurin inhibitor.
a comparing patients without AKI to all patients with AKI. p-valuesa are the results of unpaired t-test or Mann-Whitney U test for continuous variables, and χ2 test or Fisher’s exact test for categorical variables.
b comparing patients within four groups (no AKI, risk, injury, and failure). p-valuesb are the results of One-way analysis of variance or Kruskal-Wallis test for continuous variables, and χ2 test or Fisher’s exact test for categorical variables.
