Concealed allocation: an under-reported and misunderstood component of trial methodology in stroke rehabilitation - reply

摘要

We would like to thank Drs. Berger and Do [1] for making us aware of Berger's work, which includes approaches for the prevention, detection, and statistical adjustment of the effects of third-order residual selection bias because of lack of concealed allocation (CA) in randomized trials [2]. Having now acquainted ourselves with his work, we believe that our two groups probably share many values and beliefs. At a general level, we share a profound respect for the scientific method, including the necessity of observing proper methodology. More specifically, we share an interest in the problematic issue of CA in clinical trials. And finally, we would likely agree that CA is frequently misunderstood by authors and, by implication, editors and reviewers.
