The ROC curve is a statistical tool used to evaluate the discriminative capacity of a dichotomous diagnostic test. These are curves in which sensitivity is presented as a function of false positives (complementary to specificity) for different cut-off points. They are useful for choosing the most appropriate cut-off point for a test, knowing its overall performance and comparing the discriminative capacity of 2 or more diagnostic tests.
ROC曲线是一种用于评估二分诊断测试鉴别能力的统计工具。这些曲线中,敏感性是针对不同临界点的假阳性(特异性的互补指标)的函数。它们有助于为一项测试选择最合适的临界点,了解其整体性能,并比较两种或更多诊断测试的鉴别能力。
