The odds ratio is very useful; when used as a measure of association (or to describe the results of a randomised controlled treatment trial) it expresses both the strength and direction of the association (or size and direction of treatment effect). Its 95% confidence interval estimates the likely degree of sampling error and provides a test of significance at the 5% level. Authors, when reporting the results of descriptive studies, case-control studies and randomised controlled trials, should consider presenting their results this way rather than by simple significance testing with a chi squared test.
比值比非常有用；当用作关联度的度量（或描述随机对照治疗试验的结果）时，它能同时表达关联的强度和方向（或治疗效果的大小和方向）。其95%置信区间可估计抽样误差的可能程度，并提供5%水平的显著性检验。作者在报告描述性研究、病例对照研究和随机对照试验的结果时，应考虑以这种方式呈现结果，而不是通过卡方检验进行简单的显著性检验。
