Percentage of Participants With Early Allograft Dysfunction (EAD) Primary · 7 Days

EAD is a binary outcome defined by the presence of one of the following 3 outcomes: * Serum bilirubin ≥ 10 mg/dL at day 7 post-transplant * International normalized ratio (INR) ≥ 1.6 at day 7 post-transplant * Alanine Aminotransferase (ALT) or Aspartate Transaminase (AST) \> 2000 IU/L within the first 7 days post-transplant

Standard of Care (Ice)23.717.1 – 31.9
Number of Participants With Primary Non-Function Secondary · 10 Days

Primary Non-Function is defined in this study as irreversible graft dysfunction requiring emergency liver replacement during the first 10 days after liver transplantation.

Number of Participants With Post-Reperfusion Syndrome Secondary · 1 Day

Post-Reperfusion Syndrome is defined in this study as a decrease in mean arterial pressure (MAP) of more than 30% from the baseline value for more than one minute during the first five minutes after reperfusion.

Measure Biochemical Liver Function Via International Normalized Ratio (INR) Secondary · 6 Months

The international normalized ratio (INR) is a laboratory measurement of how long it takes blood to form a clot. It is calculated using the following formula: INR = (PT \[test\] / PT \[control\])\^ISI INR = international normalized ratio PT \[test\] = tested prothrombin time PT \[control\] = control prothrombin time ISI = international sensitivity index
