摘要

似然比对两个值（即病例率）进行比较，以说明两者之间的差异程度。与灵敏度和特异性相比，似然比从不同的角度增加了人们对诊断测试的信心。本文介绍了似然比的计算方法和简化方法。似然比是毒理学家了解统计学和概率论的另一个工具。

Biostatistics and Epidemiology for the Toxicologist: Likelihood Ratios.

Likelihood ratios compare two values (i.e., case rates) in order to illustrate the magnitude of the difference between the two. This ratio increases the confidence one can have in a diagnostic test from a different vantage point than that of sensitivity and specificity. The calculations of likelihood ratios are presented along with a simplified approach. Likelihood ratios are another tool the toxicologist should employ in their understanding of statistics and probability.

期刊介绍： Journal of Medical Toxicology (JMT) is a peer-reviewed medical journal dedicated to advances in clinical toxicology, focusing on the diagnosis, management, and prevention of poisoning and other adverse health effects resulting from medications, chemicals, occupational and environmental substances, and biological hazards. As the official journal of the American College of Medical Toxicology (ACMT), JMT is managed by an editorial board of clinicians as well as scientists and thus publishes research that is relevant to medical toxicologists, emergency physicians, critical care specialists, pediatricians, pre-hospital providers, occupational physicians, substance abuse experts, veterinary toxicologists, and policy makers. JMT articles generate considerable interest in the lay media, with 2016 JMT articles cited by various social media sites, the Boston Globe, and the Washington Post among others.
