Trial By Error: Disinformation About Treatments For Post-Covid Syndrome

David Tuller



By David Tuller, DrPH

Professor Trudie Chalder is a lead investigator of a series of studies of rehabilitative interventions for so-called “medically unexplained symptoms” that have failed to meet expectations but have nevertheless been promoted as demonstrating treatment success. The piece of crap known as the PACE trial is a prime example. Most famously, Professor Chalder declared at the press conference for the first PACE results, published in 2011 in The Lancet, that twice as many people in the cognitive behavior therapy and graded exercise therapy groups “got back to normal” compared to those in the other groups. This statement was false and scientifically indefensible. [In this paragraph, I initially wrote “more than twice as many people” rather than “twice as many.” I apologize for the error, which I fixed within a couple of hours.]

Professor Chalder has never publicly acknowledged or apologized for this gross misrepresentation of her study’s findings, at least as far as I have seen. Her assertion was widely disseminated by UK journalists. That is not surprising, since the British press corps has largely served as a stenographic service for the nonsense promoted by Professor Chalder and other leading lights of the biopsychosocial ideological brigades.
