Re: Cognitive behaviour therapy for the chronic fatigue syndrome: a randomised controlled trial
I would be grateful if the authors would say where the data for this trial are currently stored, as I would like to make a request to the relevant public authority for access.
I have asked both the University of Oxford and Oxford Health NHS Foundation Trust . Neither has the data.
I have also twice emailed the Principal Investigator, but not received a response.
