诊断医学研究的目的是评估和比较诊断测试的准确性，以提供有关患者疾病状态的可靠信息，从而影响患者的护理。在开发筛查工具时，研究人员通过使用简单的测量方法来评估筛查测试的区分能力，例如测试的灵敏度和特异性，以及阳性和阴性预测值。在这份简短的报告中，我们讨论了这些用于量化测试诊断能力的简单统计方法。
The aim of diagnostic medicine research is to estimate and compare the accuracy of diagnostic tests to provide reliable information about a patient's disease status and thereby influencing patient care. When developing screening tools, researchers evaluate the discriminating power of the screening test by using simple measures such as the sensitivity and specificity of the test, as well as the positive and negative predictive values. In this brief report, we discuss these simple statistical measures that are used to quantify the diagnostic ability of a test.
