How can you minimize carryover effects in a crossover trial?
Crossover trials are a type of experimental design that involve assigning participants to different sequences of treatments, with a washout period between each treatment. This allows for comparing the effects of different treatments within the same individuals, reducing the variability and confounding factors that may affect the results. However, crossover trials also have some challenges, such as the possibility of carryover effects. Carryover effects occur when the effects of one treatment persist or influence the response to the subsequent treatment, even after the washout period. Carryover effects can bias the estimates of treatment effects and compromise the validity of the trial. Therefore, it is important to minimize carryover effects in a crossover trial as much as possible. In this article, you will learn some strategies to reduce the risk of carryover effects in your crossover trial.
