To aid physicians who may be having difficulty applying the principles of decision analysis to diagnostic data according to the methods published in the past several years, the authors of this paper set out a few principles and schemes for using and interpreting diagnostic data obtained from dichotomous tests. They also present a simple BASIC program for calculating post-test probabilities from likelihood ratios and pretest probabilities that a particular disease is present in a particular patient; the program can be adapted for use on microcomputers.
为了帮助那些可能在按照过去几年发表的方法将决策分析原理应用于诊断数据时遇到困难的医生，本文作者提出了一些使用和解释从二分法检验获得的诊断数据的原则和方案。他们还给出了一个简单的BASIC程序，用于根据似然比和特定患者患有特定疾病的验前概率计算验后概率；该程序可改编用于微型计算机。
