Table 3 Associations of predictors with primary outcome (mortality)

From: Impact of acute kidney injury exposure period among liver transplantation patients

Predictor HR 95% CI P-value
A week or more from diagnosis of AKI to RRT or SCr peak    
  Unadjusted 3.11 1.92, 5.05 <0.001
  Adjusted for age, gender, diabetes, hypertension, smoking habit and liver malignancy 3.03 1.84, 4.98 <0.001
  Adjusted for age, gender, diabetes, hypertension, smoking habit, liver malignancy, total surgical time, postoperative pressor drugs and severe liver graft failure 3.68 2.16, 6.26 <0.001
A week or more from AKI to RRT only, adjusted1 2.93 1.17, 7.30 0.021
Days from AKI diagnosis to RRT or creatinine peak adjusted 1.03 1.01, 1.05 0.002
Days from AKI stage 1 to RRT or creatinine peak adjusted 1.03 1.01, 1.05 0.002
Days from AKI stage 2 to RRT or creatinine peak adjusted 1.19 1.10, 1.28 <0.001
Days from AKI stage 3 to RRT or creatinine peak adjusted 1.18 1.08, 1.30 0.001
  1. AKI: acute kidney injury; CI: confidence interval; HR: hazard ratio; RRT: renal replacement therapy; SCr: serum creatinine; 1 model applied only to patients who required RRT after LT.
