Unusually for Psychological Medicine, we publish below six letters concerning the paper by White et al. (Reference White, Goldsmith, Johnson, Chalder and Sharpe2013) on the PACE Trial. The UK Office of the Journal received 15 letters criticizing aspects of this paper, but it seemed unlikely that all of these letters originated entirely independently since a number arrived on successive days and reiterated the same points. Nevertheless, in the spirit of scientific openness we have published six of the letters which cover the main criticisms, and invited Professor White to reply to them.
