APRIL FOOL'S! 
Yes, you guessed it. Prescrire's "News Flash" revealing the contents of a report from the "Universal Medicines Agency" dated 1 April 2022 and purporting to do away with the "p value" was in fact an April fool's prank.
A humorous nudge designed to remind readers not to let the dizzying speed of medical and other news get in the way of clear thinking and careful analysis. A reminder also that, when it comes to evaluating medical evidence, an emotional appeal to democratic or other "values" is no excuse to reliquish one's grasp on solid scientific concepts and methods, including the much-maligned "p value". And to resist the temptation to give too much significance to things that are not, scientifically, significant.

40 years of "fishy business" in April
The traditional April prank by Prescrire's editors serves as an annual "booster shot" to remind us all that, in the serious business of medical information, it pays to exercise critical judgement at all times.
In April 1983 Prescrire's "special correspondent" revealed to enthralled readers the enormous interest of protryptophane in the treatment of acute senility... And ever since, the experiment has been repeated yearly in La revue Prescrire's April issue.
And on a few occasions, Prescrire's "April fish" (as the seasonal pranks are known in France) have even made it into the English edition, Prescrire International. One of these is included below, in this sampling of Prescrire's yearly "Poissons d'avril".
Greatest hits from Prescrire's annual "Poisson d'avril" prank
- Pillflix 3D°: an Innovative new manufacturing process that could revolutionise the way we solve medicines shortages (1 April 2020)
"Pillflix3D° is a new drug that can be fully personalised online and downloaded for 3D laser printing. The physician ticks the boxes "Dosage" and "Desired length of effect". The pharmacist ticks the boxes "Breakable", "Crushable" and "Soluble". The nurse confirms the "Route of administration" and ticks the boxes "Printing", "To Do" and "Done". Then the patient clicks on the size of the tablet (large, small), its shape (square, round or oval), its colour (red, white, blue) and its flavour (salted caramel, strawberry, barley water, vanilla)..."

- Innovative new research on "high dilutions" could change in the way we look at pharmacology (1 April 2019)
"While some remain mired in a sterile debate over whether or not homeopathy is "fake medicine", highly rigorous researchers have announced great strides in the area of "high dilutions", opening up a whole new era in critical thinking... These results, [reported in the April edition of La revue Prescrire], are noteworthy, since they could call into question the laws of universal gravity and the laws governing classic organic chemistry, the very foundations underlying all pharmacological principles."
