Abstract

Diagnostic tests are used to identify subjects with and without disease. In a previous article in this series, we examined some attributes of diagnostic tests - sensitivity, specificity, and predictive values. In this second article, we look at likelihood ratios, which are useful for the interpretation of diagnostic test results in everyday clinical practice.

摘要

诊断测试用于识别患有疾病和未患疾病的受试者。在本系列的上一篇文章中，我们研究了诊断测试的一些属性——敏感性、特异性和预测值。在第二篇文章中，我们将探讨似然比，它在日常临床实践中对解释诊断测试结果很有用。
