Dear Medical Research Council,
"Comparison of adaptive pacing therapy, cognitive behaviour
therapy, graded exercise therapy, and specialist medical care for chronic fatigue syndrome (PACE): a randomised trial"
I would like access to the full raw data from the PACE Trial.
I particularly require the data relating to the changes measured for each individual participant (i.e. not just the average measurements), at baseline and at 52 weeks for the primary outcomes for each of the measured groups in the Trial (The SMC, GET, CBT and APT groups.)
The same measurements for the secondary outcomes is also required.
I also require the data relating to the changes measured for individual participants, and the average changes, in each subgroup in the study (i.e. subgroups under each of the different diagnostic criteria.)
Dear Mr Courtney,

We are looking into whether the Medical Research Council hold any
