Abstract
In this article we provide an introduction to the use of likelihood ratios in clinical ophthalmology. Likelihood ratios permit the best use of clinical test results to establish diagnoses for the individual patient. Examples and step-by-step calculations demonstrate the estimation of pretest probability, pretest odds, and calculation of posttest odds and posttest probability using likelihood ratios. The benefits and limitations of this approach are discussed.
摘要
在本文中，我们介绍似然比在临床眼科中的应用。似然比有助于最佳利用临床检查结果来为个体患者进行诊断。通过实例和逐步计算展示了如何使用似然比来估计验前概率、验前比值，以及计算验后比值和验后概率。同时还讨论了这种方法的优点和局限性。
