Abstract
In clinical trials sponsored by Merck the unblinded statistician is typically an employee of the company. From a pharmaceutical industry perspective, advantages of this approach include ensuring that the unblinded statistician is knowledgeable regarding the experimental treatments, therapeutic area and study objectives; that the quality of the analysis conforms to rigorous standards; and that the allocation schedule, database and interim results are kept confidential. These advantages are felt to outweigh any potential disadvantages.
