Odds ratios and predicted probabilities are not the same thing, as odds ratios are a measure of association between two variables, while predicted probabilities estimate the probability of an outcome based on a set of predictors. However, they can be related in certain situations, such as when the predictors have a linear relationship with the logarithm of the odds ratio, or when the outcome is rare and the odds ratio approximates the relative risk, which can be used to calculate predicted probabilities. In general, though, the two should not be confused or used interchangeably.
