Updates on the validity of ROCKET-AF conclusion based on issues with point-of-care INR results: Defence or Defiance?
I believe that interested readers would like to be informed on the recent published letter from Dr JR Powell regarding his concerns with point-of-care INR readings used in the ROCKET-AF and the study author's response:
However I do not believe NEJM has published any letters from Thomas Marcinicak mentioned in this BMJ article. No free access to datasets has been offered as far as I can tell.
For some, the veil of secrecy that remains even when significant allegations of the study validity has been openly voice, will only result in a slow erosion of confidence from lingering doubts
