Abstract. We provide a program to illustrate interactions between treatment and
covariates or between two covariates by using forest plots under either the
Cox proportional hazards or the logistic regression model. The program is
flexible in both the possibility of illustrating more than one interaction
at a time and variable specifications of scale.
