Last time, we give a SAS example of Risk Difference to test if two groups are experiencing the same proportion of a certain event. In order to understand the topic better, we will go over Risk Ratio. Definition: Risk Ratio or Relative Risk (RR) is the probability that an event occurs i...
其实在临床科研中,也有“真假美猴王”的存在,那就是相对危险度(Relative Risk),一种我们在队列研究或者临床试验研究中常用于反应暴露(包括某种特征、某种行为或接触某种研究物质)与结局关联强度的指标。细心的同学可能会发现,相对危险度也叫危险比(Risk Ratio)或率比(Rate Ratio),虽然它们的缩写都是RR,但是所代表的...

在Logistic回归分析中就涉及到odds ratio和Relative Risk，这里有个知乎讲得就很好了，就不赘述了 Reference： https://medium.com/@chungyizhen/%E7%82%BA%E4%BB%80%E9%BA%BC%E9%83%BD%E7%94%A8-%E5%8B%9D%E7%AE%97%E6%AF%94-odds-ratio-or-%E8%80%8C%E4%B8%8D%E6%98%AF...
Let’s now go back to our more practical example: the observations of statin use and the incidence of AD (Figure 4). Note that this study compared high-exposure vs. low-exposure statin users, but excluded non-users as a control group when calculating relative risk. They did note (Figure...
相对危险度你可能还不明白是什么?但是缩写RR值你恐怕在很多在文献中都看过,它全称是Relative Risk。 据相关教材介绍,相对危险度是医学研究的重要指标,特别是队列研究和随机对照研究,相对危险度是经常被计算的指标。 在队列研究中,RR=暴露组发病率(或死亡率)/对照组发病率(或死亡率) ...
(Weber and Hsee 1998, 1999). Both individual andgroup differencesin preference for risky decision alternatives and situational differences inrisk preferencehave been shown to be associated with differences in perceptions of the relative risk of choice options, rather than with differences in attitude ...
