 This study revisited seven major medical journals to assess whether their recommendations on statistical analysis of pilot studies have changed practice. The authors also conducted a survey to identify the methodological components in registered research studies that are described as pilot or feasibility studies and discovered the policies of grant awarding bodies and journal editors regarding these types of studies. The study found 54 pilot or feasibility studies published in 2007-08, with 26 being pilot studies of interventions and the remainder feasibility studies. Most of these studies incorporated hypothesis testing, a control arm, and randomization procedures. However, only eight out of 90 pilot studies identified by an earlier review led to subsequent main studies. The authors also found that there was no clear distinction in use of the terms pilot and feasibility, with five journal editors responding to their survey indicating a reluctance to publish studies described as pilot. Overall, the study suggests that pilot studies are still poorly reported, with an emphasis on hypothesis testing rather than other methodological components. The authors propose clarifying terminology to help authors report these types of studies appropriately and explicitly.
