ASSESSMENT OF THE CLINICAL PERFORMANCE OF LAB TESTS

本研究主要关注影响临床疗效的因素， 诊断实验室测试。提出了一种新的图解法（成本-误差图）， 为纳入流行率和错误分类的成本而制定 在测试性能上，影响实用性的两个重要因素 诊断测试与接收器操作特性图不同， 实验室检测的临床效果可以通过成本进行比较， 一系列可能的患病率和错误分类的误差图 成本未来的工作将开发软件，以促进 制作成本误差图。

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.
