I have a logistic regression in which most of the predictors are binary, but two are continuous (e.g., age). I am planning to use a simple forest plot to visualise the odds ratios for readers. However, because they are measured on different scales, the odds ratios for the continuous predictors look tiny in comparison to the odds ratios for the binary predictors (as an increase of 1 year of age of course leads to only a small increase in the probability of the outcome).
This gives the visual impression that age is an unimportant predictor, but it is not, for if we were to dichotomize age into a binary variable like the others (e.g. above/below the median) its odds ratio becomes large. What are best practices for clearly visualizing results for readers in this situation? It seems strange to put variables on different scales all on the same graph, but it also seems strange to dichotomize a variable solely for presentation purposes.
