Parachute use to prevent death and major trauma related to gravitational challenge: systematic review of randomised controlled trials
http://www.ncbi.nlm.nih.gov/pmc/article ... 701459.pdf
Abstract
Objectives
To determine whether parachutes are effective in preventing major trauma related to gravitational challenge.
Design
Systematic review of randomised controlled trials.

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.

Conclusions
As with many interventions intended to
prevent ill health, the effectiveness of parachutes has
not been subjected to rigorous evaluation by using
randomised controlled trials. Advocates of evidence
based medicine have criticised the adoption of
interventions evaluated by using only observational
data. We think that everyone might benefit if the most
radical protagonists of evidence based medicine
organised and participated in a double blind,
randomised, placebo controlled, crossover trial of the
parachute
