Such determinations can become complicated because of the need for specifying nuisance parameters such as the error variance, and the choice for a clinically meaningful treatment difference may not be straightforward. However, adjustment of sample size with proper modification of Type I error may result in an overpowered study, which wastes resources, or an underpowered study, with little chance of success. A traditional clinical trial fixes the sample size in advance and performs the analysis after all subjects have been enrolled and evaluated.
