Physical therapy researchers are interested in how beneficial an intervention is or the “treatment effect.”  There are many measures of treatment effect that are applicable for understanding the efficacy and effectiveness of health interventions. Given that each treatment effect has its own set of advantages and disadvantages, understanding these characteristics can help guide which measure is most appropriate for a specific study. This article presents the more common treatment effects for both dichotomous and continues outcomes.  The overall aim is to serve as a guide to newer physical therapy researchers on using and interpreting treatment effects.
KEY WORDS: Treatment effects, Relative measures of effect, Absolute measures of effect.
