Recruitment strategies for sarcopenia trials: lessons from the LACE randomized controlled trial

Sarcopenia is rarely diagnosed and is not recorded electronically in routine clinical care, posing challenges to trial recruitment. We describe the performance of four components of a strategy to efficiently recruit participants with sarcopenia to a trial of perindopril and/or leucine for sarcopenia: primary care vs. hospital recruitment, a comparison of central vs. local telephone pre‐screening, performance of a questionnaire on physical function conducted as part of the pre‐screening telephone call, and performance of bioimpedance measurement to identify low muscle mass.
