In an article which appeared online on November 22, remarks made by Professor Henry Nasrallah, University of Cincinnati Medical Center, were mistakenly attributed to Dr Jeffrey A. Lieberman MD, Chairman, Department of Psychiatry, Columbia University, New York. The views expressed were those of Professor Nasrallah. We apologise for the error and any distress caused. Dr Lieberman has not previously spoken to PharmaTimes about the CATIE study. An update on this landmark study will be the subject of an online article in the New Year.
