It's a follow-up to a previous article bemoaning the lack of a randomised controlled trial of parachutes and arguing that they should not therefore be accepted as a valid 'treatment' for falling out of an aeroplane (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC300808/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC300808/). Both this article and its predecessor were published in the Christmas issue of the BMJ, where funny papers with a semi-serious point (in these cases, the ongoing debates in medicine about the superiority of RCTs over other forms of clinical evidence) are common. My favourite of this genre is "Does Peppa Pig encourage inappropriate use of primary care resources?" (https://doi.org/10.1136/bmj.j5397 https://doi.org/10.1136/bmj.j5397) critiquing the clinical practice of Dr Brown Bear, a fictional cartoon GP.
