Diagnosis of liver diseases by classification of laboratory signal factor pattern findings with the Mahalanobis·Taguchi Adjoint method

There are many autoimmune liver diseases in which diagnosis is difficult so that overlap is accepted, and this negatively affects treatment. The initial diagnosis is therefore important for later treatment and convalescence. We distinguished autoimmune cholangitis, autoimmune hepatitis and primary b...

Summary:There are many autoimmune liver diseases in which diagnosis is difficult so that overlap is accepted, and this negatively affects treatment. The initial diagnosis is therefore important for later treatment and convalescence. We distinguished autoimmune cholangitis, autoimmune hepatitis and primary biliary cirrhosis by the Mahalanobis·Taguchi Adjoint (MTA) method in the Mahalanobis·Taguchi system and analyzed the pattern of factor effects by the MTA method. As a result, the characteristic factor effect pattern of each disease was classified, enabling the qualitative evaluation of cases including overlapping cases which were difficult to diagnose.
