Abstract

YOU RECALL from the first of our two articles concerning clinical decision analysis1 that your patient is a middle-aged man with heart failure from an idiopathic dilated cardiomyopathy. You are trying to decide whether to recommend anticoagulation with warfarin to prevent systemic or pulmonary thromboembolism.

In this article, we will show you how to interpret the results and generalizability of a clinical decision analysis(Table).
