Odds ratio(OR)从字面上可看出,是两个odds的ratio,其用于: 在病例对照研究(case-control study)中,分析暴露风险因素与疾病(或者用药)的关联程度;主要是反映暴露与疾病之间关联强度的指标,OR常适用于病例对照研究,也可以运用于前瞻性的研究(当观察时间相等时) 与其相似的有个指标relative risk(RR),其可以理解为ris...

An odds ratio of exactly 1 means that exposure to property A does not affect the odds of property B. An odds ratio of more than 1 means that there is a higher odds of property B happening with exposure to property A. An odds ratio is less than 1 is associated with lower odds. Howev...
Risk Ratio means the probability of an event occurring in group 1 compared to the probability of the same event occurring in group 2. Conclusion: Risk ratio compares the probability of the occurrence of the same event in two groups. In addition, we can use the Risk Difference to check if ...
The concept of odds ratio originated from gambling wherein the odds of an event A against another event B is defined as the ratio P(A)/P(B). From: Reliability Modelling and Analysis in Discrete Time, 2018 About this pageAdd to MendeleySet alert ...
Formula: Risk Ratio (Relative Risk)= P(event in group1)/P(event in group 2) Interpretation: RR ≈ 1⇒ The proportion of events are similar in group 1 and group 2. RR » 1⇒ Increased probability of events among those in group 1 compared to group 2. ...
In the previous article, we explained that the risk ratio (RR) and the odds ratio (OR) are measures of effect. In this article, we will discuss in more detail the properties of the RR and the OR and how those 2 effect measures are related. Table 1 summarizes risks, odds, RRs, and...

Many authors present this formula as log( p/[1-p] ) = Xb which also means p / (1-p) = exp(Xb) The language here is sometimes confusing because some authors call this theodds ratio. Englishwise, they are correct: it is theoddsand theoddsare based on a ratio calculation. It isnot...
