No randomised controlled trials of parachute use have been undertaken


This one is straight out of the Department of the Bleeding Obvious.

Still, apart from that one line the article is both useful and highly informative and not at all lighthearted or a p**s-take

My first take on the article was that it was intended as humor, which surprised me greatly because this is a very prestigious medical journal. Then I noticed that this actually has a considerable number of real citations. The point of the article (which I initially missed) is that when the science behind a treatment is sound, we should not wait for the clinical trials to complete (a process of years) before making that treatment available. If I had stopped laughing and read a little more carefully ...

BMJ wrote:
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.


[emphasis added]

... then I might have noticed the invitation to toss the critics out of an airplane. Wink
