🧟 Beware of the zombie trials:

More than one-quarter of a subset of manuscripts describing randomized clinical trials submitted to the journal Anaesthesia between 2017 and 2020 seemed to be faked or fatally flawed when their raw data could be examined, editor John Carlisle reported. He called these ‘zombies’. But when their raw data could not be obtained, Carlisle could label only 1% as zombies.

Good thing that science is a strong link problem, because too many of the links are just sawdust and dreams. (via Derek Lowe)
