摘要相对危险度（ RR）、风险比（ HR）和比值比（ OR）常被用于衡量暴露因素和结局的关联强度，是公共卫生学领域中重要的统计指标。这些指标的计算原理和公共卫生学意义存在差异，但部分研究人员在应用这些指标或解释研究结果时常误用或混淆 RR、 HR和 OR值。因此本文探讨了三者的关联和区别，以及在队列研究和病例对照研究中 RR、 HR和 OR值的正确选择和使用。

abstractsRelative Risk ( RR), Hazard Ratio ( HR), and Odds Ratio ( OR) are commonly used statistical measures in the field of public health to assess the magnitude of the effect of exposure factors on outcomes. These indicators have different calculation principles and implications in public health. However, a few researchers misused or misinterpreted RR, HR, and OR values when interpreting study results. Therefore, this article explores the relationships and differences among these measures, as well as the correct selection and application of RR, HR, and OR in both cohort study and case-control study.
