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...

Analysis_Meta-analysis_Odds Ratio.Case-control studies of dichotomous outcomes (e.g. healed or not healed) can by represented by arranging the observed counts into fourfold (2 by 2) tables. The separation of data into different tables or strata represents a sub-grouping, e.g. into age ...
By plugging these numbers into the odds ratio formula, we can calculate the odds ratio to assess the relationship between visiting a petting zoo and becoming infected byE. coli. In case-control studies, all infected cases go in the numerator while the uninfected controls go in the denominator....
This probability is derived through an odds ratio proof for the common conditional odds ratio of Cochran Mantel Hansel showing theta equals one. Subsequently, the probability formula is obtained and the hazard ratio expression derived. However, the new relation of this proof is to show that logits...
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 ...
The calculation of the odds ratio is quite simple. The formula is as follows: Where “PG1” represents the odds of the event of interest for Group 1, and “PG2” represents the odds of the event of interest for Group 2. Another way to represent the formula is in table format: Standar...
Dietary potassium can play an important role in decreasing inflammatory factors as a protective factor for cancers. In this case-control study, we aimed to assess the possible association between dietary potassium intake and the risk of breast cancer (BC) among Iranian adult women. Methods The pre...
