在本文中,我们讨论了计算敏感性、特异性、阳性预测值和阴性预测值的基本知识。我们已经讨论了这些措施的优点和局限性,并提供了我们应该如何在日常临床实践中使用这些措施。我们还说明了如何在结合两个测试时计算灵敏度和特异度,以及如何将这些结果用于我们的患者的日常实践。
In this article, we have discussed the basic knowledge to calculate sensitivity, specificity, positive predictive value and negative predictive value. We have discussed the advantage and limitations of these measures and have provided how we should use these measures in our day-to-day clinical practice. We also have illustrated how to calculate sensitivity and specificity while combining two tests and how to use these results for our patients in day-to-day practice.
