Re:Research into CFS/ME

As a mathematician with ME, I would like to point out that I do not
reject the PACE study. I do however reject its conclusions, and that is
very different.

It has taken me many hours of analysis to come to that conclusion:
the data is complex. However an NNT of 7 or 8 for a heterogeneous group
suggests that a generalised conclusion is inappropriate, particularly when
there is no reliable quantitative assessment to back up the results.
