[pullquote]The Factor V Model for prediction of 21-day Transplant Free Survival demonstrates the expected transplant free survival for patients with acute liver failure.[/pullquote]

Formula :

-0.6969 + (0.0516 * Factor V %) -(0.5801 * Use of Vasopressor)-(0.0953 * Total Bilirubin) – (0.7146 * Etiology of ALF) – (0.2914 * Grade of Encephalopathy);

Explanation of Result :

Expected 21-day transplant free survival %.
