ASSESSMENT OF THE CLINICAL PERFORMANCE OF LAB TESTS

本研究重点探讨了影响维拉帕米临床疗效的因素 诊断性实验室测试。提出了一种新的图解方法(成本-误差图)。 为纳入流行率和错误分类的成本而开发的 在测试性能上，影响实用性的两个重要因素 诊断性测试。与接收器工作特性曲线不同， 实验室检测的临床疗效可以很容易地通过成本来比较- 在一系列可能的流行率和错误分类上的错误图 成本。今后的工作将在开发软件方面进行，以方便 制作成本-误差曲线图。

This study focused on factors that impact on the clinical efficacy of diagnostic laboratory tests. A new graphical method (cost-error plot) was developed for incorporating prevalence and the costs of misclassification on test performance, two important factors that affect the practicality of diagnostic tests. Unlike receiver operating characteristic plots, the clinical efficacy of laboratory tests can be readily compared by cost- error plots over a range of possible prevalence and misclassification costs. Future work will be done developing software to facilitate production of cost-error plots.
