Retraction note

This article has been retracted by the authors after discovering an error in the data. The two CATIE-AD articles included in the systematic review [1, 2] should not have been treated as separate trials as this led to data from some trial participants being included twice in the meta-analysis. As a result, large sections of the article are inaccurate. To avoid confusion this article has been retracted and the authors have been given the opportunity to resubmit their corrected data.
