In the previous two articles in this series on biostatistics, we examined the properties of diagnostic tests and various measures of their performance in clinical practice. These performance measures vary according to the cutoff used to distinguish the diseased and the healthy. We conclude the series on diagnostic tests by looking at receiver operating characteristic curves, a technique to assess the performance of a test across several different cutoffs, and discuss how to determine an optimum cutoff.
在本生物统计学系列的前两篇文章中，我们研究了诊断测试的特性以及它们在临床实践中的各种性能指标。这些性能指标会根据用于区分患病和健康状态的临界值而有所不同。我们通过研究受试者工作特征曲线来结束关于诊断测试的系列文章，这是一种评估测试在几个不同临界值下性能的技术，并讨论如何确定最佳临界值。
