    Summary: "This book provides practical guidance for statisticians, clinicians, and researchers involved in clinical trials in the biopharmaceutical industry, medical and public health organisations. Academics and students needing an introduction to handling missing data will also find this book invaluable. The authors describe how missing data can affect the outcome and credibility of a clinical trial, show by examples how a clinical team can work to prevent missing data, and present the reader with approaches to address missing data effectively. The book is illustrated throughout with realistic case studies and worked examples, and presents clear and concise guidelines to enable good planning for missing data. The authors show how to handle missing data in a way that is transparent and easy to understand for clinicians, regulators and patients. New developments are presented to improve the choice and implementation of primary and sensitivity analyses for missing data. Many SAS code examples are included - the reader is given a toolbox for implementing analyses under a variety of assumptions"--Provided by publisher.

    Tolerance of a cerebral hemisphere to permanent interruption of the ipsilateral carotid artery or to prolonged operative clamping of this vessel, can be determined preoperatively by a noninvasive technique combining the use of the ocular pneumoplethysmograph with compression of the proximal part of the common carotid artery. This technique is essential for the management of proximal lesions of the brachiocephalic arterial system to avoid the use of bypass grafts and to permit a supraclavicular approach rather than thoracotomy or a median plane sternotomy.
