Notes

• In this calculator, mcg is the abbreviation for micrograms.

 
Equations used
 

RiskScore = (0.957 * ln(Creat)) + (0.378 * ln(Bili)) + (1.12 * ln(INR)) + (0.643 * Cause)

Survival = Dayse(RiskScore-1.127)

 

 

Calculation Details and Variables

• Equation parameters such as Cause, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (0), represent the values that will be used.
