För en vecka sedan publicerades en ny omanalys av PACE-studiens data i tidsskriften Fatigue: Biomedicine, Health & Behavior. Omanalysen visar att de slutsatser som PACE-forskarna drog 2011 saknar stöd i datan. Författarna menar att påståendet att kognitiv beteendeterapi och gradvis ökad träning skulle kunna hjälpa vid ME/CFS är missvisande. Dessutom påpekar författarna att studien har uppenbara metodologiska svagheter.

None of the changes made to PACE recovery criteria were adequately justified. Further, the final definition was so lax that on some criteria, it was possible to score below the level required for trial entry, yet still be counted as ‘recovered’. When recovery was defined according to the original protocol, recovery rates in the GET and CBT groups were low and not significantly higher than in the control group (4%, 7% and 3%, respectively)
