Application of Indicators, Predictors and Diagnostic Indices in Coagulation Disorders

Abstract
A recently described theoretical model for the evaluation of binary and continuous diagnostic variables by indicators and predictors, is in the present study applied to a self-administered-questionnaire for obtaining a medical history of different blood coagulation disturbanoies (binary variables).The diagnostic power of each question is calculated by indicators and predictors. The total diagnostic capacity of the questionnaire is expressed by an anamnestic or summation index.The questionnaire was shown to be able to separate healthy individuals from diseased ones. A rank order of the diagnostic capacity of the questions, built upon indicators and predictors, is presented.
