P2P final report: the Oxford definition impairs progress, may cause harm and should be retired, just like the PACE trial that used them

@ Ann Intern Med., 16 June 2015:

  "Furthermore, the multiple case definitions for ME/CFS have hindered progress. In particular, continuing to use the Oxford definition may impair progress and cause harm. Therefore, for progress to occur, we recommend that this definition be retired; the ME/CFS community concur on a single case definition (even if it is not perfect); and patients, clinicians, and researchers agree on a definition for meaningful recovery."
