Mayo scoring system for predicting the need for liver transplantation in primary biliary cholangitis

R = [0.871 x log_e serum bilirubin (mg/dL)] - [2.53 x log_e serum albumin (gm/dL)]

+ [0.039 x age (years)] + [2.38 x log_e prothrombin time (seconds)]

+ [0.859 x edema score]

Edema score

0 = no edema

0.5 = diuretic-controlled edema

1.0 = diuretic-resisitant edema

Survival function [S(t)]

1 year = 0.970

2 years = 0.941

3 years = 0.883

4 years = 0.774

5 years = 0.721

6 years = 0.651

Calculated patient survival = S(t)^{exp(R - 5.07)}

Survival probability at one year = 0.970^{exp(R - 5.07)}

Survival probability at three years = 0.883^{exp(R - 5.07)}
