Recenzje

'David and Carole Torgerson have written an important book about an important topic...After introducing the "breathtaking simplicity" and "beauty" of the randomized trial design [they] outline the key features of well-designed, well-conducted and well-analysed randomised trials, using illustrative examples from health care, education, criminal justice and other fields. The book is a veritable treasure trove of information and advice' - Sir Iain Chalmers, Editor, James Lind Library
