Abstract

Objectives To determine whether parachutes are effective in preventing major trauma related to gravitational challenge
Design Systematic review of randomised controlled trials
Data sources Medline, Web of Science, Embase, and the Cochrane Library databases; appropriate internet sites and citation lists.
Study selection Studies showing the effects of using a parachute during free fall
Main outcome measure Death or major trauma, defined as an injury severity score > 15
Results We were unable to identify any randomised controlled trials of parachute intervention

Thank you to Heike Fabig and Lisa Gombinski for reminding of all this.
