Design and analysis of crossover study designs. Understand the strengths and limitations of each type of study design, as applied to a particular research purpose. A crossover design is a repeated measurements design such that each experimental unit (patient) receives different treatments during the different time periods, i.e., the patients cross over from one treatment to another during the course of the trial.
