It is Mahalanobis-Taguchi (MT) system to give the standard to evaluate a process of diagnosis of the doctor commonly. When Mahalanobis distance (MD) is calculated using MT system, it can be grasped as a unitary statistic. MD was calculated using data of fulminant hepatitis and acute on chronic hepatic failure, and a change of MD was compared with the outcome of patients. As a result, it was expressed for the numerical unified value that the data which changed complicatedly. When MD increase, the condition of a patient turns worse.
