In binary logistic regression analysis within statistical theory, odds ratios serve as a metric to compare the likelihood of a dichotomous outcome event occurring between two distinct groups or under varying conditions of independent variables. The concept formalizes the relationship where an odds ratio greater than unity indicates increased relative probability in the first group compared to the reference, while values less than one indicate decreased relative probability. This theoretical construct allows for the interpretation of model coefficients by exponentiation (e^β), thereby quantifying multiplicative changes in event probabilities rather than additive ones characteristic of linear models.
