[Clinical use of a minicomputer in the evaluation of chemico-clinical parameters in the diagnosis of hepato-biliary-pancreatic diseases of surgical significance. 3 methods compared].
Bayes theorem; multivariance analysis, and the discriminating function of Mahalanobis applied to sixteen laboratory examinations employed in the diagnosis of diseases of the extrahepatic bile ducts and pancreas gave the following results: 1) the weight of each test was first measured in general terms, and then with regard to different levels of differentiation, with a classification in decreasing order in each case; 2) little redundancy was noted, and few examinations were of relatively negligible importance; furthermore, combinations of several tests did not lead to positive results; 3) reclassification according to the formula of Bayes and by means of the discriminating function proved sound supports for clinical decision, since they provided 70% and 80% of exact classification respectively; 4) the importance of the minicomputer in the construction of experimental diagnostic models was substantiated.
