Abstract

Pilot studies, when properly designed and implemented, are an important tool that provide critical information for the development and potential success of a subsequent, larger trial. In fact, these small-scale studies are commonly used to assess the feasibility of whether a larger trial should be initiated. A popular investigator question is whether a pilot study requires a formal statistical power calculation. In general, the answer is “no”; however, the sample size needs to be justified on the basis of the goal of the pilot study.
