 This study revisit seven major medical journals to assess whether their recommendations on statistical analysis of pilot studies have changed practice. Additionally, the authors conducted a survey to identify methodological components in registered research studies that are described as pilot or feasibility studies. They found that 54 such studies were published in 2007-08, with most incorporating hypothesis testing and randomization procedures. However, only eight out of 90 pilot studies identified by the earlier review led to subsequent main studies. The authors suggest that authors should be aware of the different requirements of pilot studies, feasibility studies, and main studies and report them appropriately. They also propose clarifying terminology in the definitions of feasibility and pilot studies. This article was authored by Cooper-Cindy L., Campbell Michael J., Array Mubeshear, and others.
