Note: The Child-Pugh score is calculated by adding the scores of the five factors and can range from 5-15. Child-Pugh class is either A (a score of 5-6), B (7-9), or C (10 or above). Decompensation indicates cirrhosis with a Child-Pugh score of 7 or more (class B). This level has been the accepted criterion for listing for liver transplantation.
