This medical paper found in a birdsite reply just made my day:

"Parachute use to prevent death and major trauma when jumping from aircraft: randomized controlled trial"

@leah es ist so großartig, von vorne bis hinten 😂 Und die Fotos! 😂

@rami das muss ich mir morgen echt noch mal im ganzen gönnen. Danke!

@leah @rami related to this (prior work):

"Parachute use to prevent death and major trauma related to gravitational challenge: systematic review of randomised controlled trials"

😁

@rami wait

were they testing this via parked airplanes?

I can't see any other way that they could have a mean speed of 0 kilometers per hour and a mean height of 0.6 meters

@ben @rami "However, the trial was only able to enroll participants on small stationary aircraft on the ground, suggesting cautious extrapolation to high altitude jumps."

@BestGirlGrace @ben @rami

I like the correction

Also the paper gets better as it goes on lol. It starts out a farce, and then as it goes it becomes honestly just a lot of fun making a great point about study design.

> Most of the participants who were randomized were study investigators.

@rami This answer tried a different statistical analysis of the data, suggesting that jump height was the deciding factor in the results.

@rami This is a joke study. The aircraft in question was grounded and stationary during the experiment.
