ASSESSMENT OF THE CLINICAL PERFORMANCE OF LAB TESTS

本研究主要探讨了影响 诊断实验室检查的临床疗效。新图形 方法（成本误差图）被开发来证明患病率， 错误分类对测试性能的成本，两个重要的 影响诊断测试实用性的因素。 与受试者操作特征图不同， 实验室检测的有效性可以通过成本误差进行比较 一系列可能的患病率和错误分类的图 成本研究报告的手稿正在编写中。未来的工作将 注重开发软件，以方便生产成本的错误 情节

This study focused on the factors that have an impact on the clinical efficacy of diagnostic laboratory tests. A new graphical method (cost-error plot) was developed to demonstrate prevalence and costs of misclassification on test performance, two important factors that affect the practical usefulness 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 prevalences and misclassification costs. A manuscript of the study is being prepared. Future work will focus on developing software to facilitate production of cost-error plots.
