What exactly is the Norway Cochrane re-analysis of the PACE data supposed to achieve?
[Edit: I am not sure if this is just the next update or a special edition just for PACE.]
Unless a major error is uncovered or the re-analysis is going to use different thresholds (such as the ones set out in the original protocol), then merely redoing the same analysis is just going to confirm the previous one, adding nothing to the debate except another round of back-patting from the ivory towers.
Is it supposed to demonstrate that PACE did not fake data or that they are not incompetent?
A faker would have already cleverly faked the data and then just sent that over. I do not believe the data was faked, and I doubt anyone seriously believes it was. What critics are really objecting to is the post-hoc protocol changes, the inadequate justification and lack of details, and possibly the timing and potential COI. On the issue of incompetence, the threshold for normal physical function certainly reflects poorly enough on the researchers and professionals involved.
Objections have also been raised which have nothing to do with the data itself, such as the nature of the improvements, the interpretation of the results, and the generalizability of the cohort. The Norway Cochrane re-analysis of PACE data will probably function as a good publicity stunt while failing to address the key criticisms.
