"A book to read from beginning to end.... Clinical Trials in Psychiatry covers all the most important issues and will be useful to all clinicians who are involved in conducting, or using the results of, clinical trials. It provides a highly persuasive account of the unique scientific advantages of randomised trials for those who remain unconvinced. It is very readable."
