OMG this is so old. Funny though

Submission title doesn't match the main findings:

We have performed the first randomized clinical trial evaluating the efficacy of parachutes for preventing death or major traumatic injury among individuals jumping from aircraft. Our groundbreaking study found no statistically significant difference in the primary outcome between the treatment and control arms. Our findings should give momentary pause to experts who advocate for routine use of parachutes for jumps from aircraft in recreational or military settings.

The full title of the paper is Parachute use to prevent death and major trauma when jumping from aircraft: randomized controlled trial.

It's also from 2018.

That said, clearly a seminal paper, well worth the read.
