Review
'This is an easy-to-read, informative collection of papers which gives comprehensive coverage of the subject matter from a range of perspectives...The chapters on the methodology of preventation trails and the sources of high-risk participants and the costs of finding and recruiting them are outstanding and should be required reading for all scientists engaged in studies of disease prevention...It should be on the bookshelves of both doctor's offices and research facilities.' Journal of the National Cancer Int. 84:5, 1992
