  1. Responses presented were reported by 55 trialists who reported progression criteria in their publication, and whose pilot trials had completed
  2. aAlthough 19 respondents completed survey 1, only 14 described that their pilot trial was in the reporting or dissemination stage and so responded to the questions presented in this table
  3. bRespondents were asked whether they would conduct further feasibility assessment only where they considered their pilot trial to be feasible with changes or where feasibility was unclear
