SR Print(0) ID 1183877365 T1 Examples of Likelihood Ratios T2 Users' Guides to the Medical Literature: A Manual for Evidence-Based Clinical Practice, 3rd ed YR 2015 FD 2015 PB McGraw-Hill Education PP New York, NY SN 978-0-07-179071-0 LK jamaevidence.mhmedical.com/content.aspx?aid=1183877365 RD 2024/09/13 AB Other chapters of this book have made the case for the usefulness of likelihood ratios (LRs) in the process of diagnosis (see Chapter 16, The Process of Diagnosis, and Chapter 18, Diagnostic Tests). In this chapter, we present some examples of LRs, along with their associated 95% confidence intervals (CIs), for many diagnostic tests. For each test, we describe the population to whom the test was applied and the range of prevalence (pretest probability) found for each target condition (disease). Our choice of conditions has been idiosyncratic and represents the interests of the authors. We restricted ourselves to tests in current use and so do not offer a technical description of the tests. The authors conducted all searches and summaries, without duplicate adjudication of eligibility or data extraction.
