Odds Ratio (Syn: cross-product ratio, relative odds) The ratio of two odds. The term odds is defined differently according to the situation under discussion. Consider the following notation for the distribution of a binary exposure and a disease in a population or a sample:... ... Acces...
However, the literature on selecting a particular category of the outcome to be modeled and/or change in reference group for categorical independent variables and the effect on statistical significance, although known, is scantly discussed nor published with examples. In this article, we provide an ...
Odds ratio, risk ratio, and prevalence ratio are some of the measures of association which are often reported in research studies quantifying the relationship between an independent variable and the outcome of interest. There has been much debate on the issue of which measure is appropriate to rep...

Odds attached to an event “having an illness” are, formally, the following ratio, where p denotes the probability of having the illness: $$ \text{Odds}=\frac{p}{1-p}\:. $$ Let there be a factor of risk to which a group E is exposed and a group NE is not exposed. The cor...

reference group to the effect of increasing dTAC. An interaction term was incorporated into the models to assess the interaction between smoking status and dTAC tertile concerning the odds of lung cancer (LC). The P-value for interactions was determined using the likelihood ratio test. The same ...
In these circumstances, the rate ratio of interest can be assessed through the mortality odds ratio (MOR), given appropriate selections of reference occupation(s) and reference disease(s). The reference occupation should be chosen with a view to three aspects of validity: (1) comparability of ...
Odds ratio = (odds in exposed group) / (odds in not exposed group) = 0.205 / 0.01 = 20.5 Thus using the odds ratio, this hypothetical group of smokers has 20 times the odds of having lung cancer than non-smokers. The question then arises: is this significant?
