Chalder fatigue scale
The Chalder fatigue scale (sometimes known as the Chalder scale) is a symptom scale created by Trudie Chalder and colleagues used to measure tiredness in the PACE trial.

Recovery claims
In a 2011 article in the Guardian UK newspaper professor Chalder was quoted as saying "twice as many people on graded exercise therapy and cognitive behaviour therapy got back to normal" which is not supported by the PACE trial results.

Controversy
In 2000 Chalder & fellow researchers were accused of "unsupported conclusions derived from faulty analyses", and responded that "we've been attacked by gremlins" who changed the data on their manuscript.
