The odds ratio, often denoted as Exp(B) in logistic regression output, quantifies the change in odds of the dependent variable occurring (or the odds of being classified in a particular category) for a one-unit increase in the predictor variable. If Exp(B) is greater than 1, it indicates an increase in odds; if it is less than 1, it indicates a decrease in odds.
