TG-ROC, a template for Microsoft-EXCEL, represents a novel, easy-to-handle approach for selecting cut-off values in quantitative diagnostic tests. In addition to graphical representations of test efficiency, Youden index and likelihood ratios as functions of the preselected cut-off value, the software supports the definition of an intermediate range of test results. For this purpose, two cut-off values are established that realise a pre-selected accuracy level (e.g., 90 or 95% sensitivity and specificity) which can be specified by the user.
TG-ROC是一个用于Microsoft-EXCEL的模板，它代表了一种新颖且易于操作的方法，用于在定量诊断测试中选择临界值。除了以图形表示测试效率、约登指数和作为预选临界值函数的似然比外，该软件还支持定义测试结果的中间范围。为此，确定两个临界值，以实现用户可以指定的预选准确度水平（例如，90%或95%的灵敏度和特异性）。
