". . . the book edited by Gatsonis and Morton fills a gap and seems very valuable for applied statisticians interested in the field of comparative effectiveness research particularly due to the selection of relevant topics and the scientific quality of the individual chapters written by leaders in the field."~Christian Stock, Biometrical Journal"In summary, the book covers a wide range of topics in CER with a good balance of methodology and practical considerations. Given that CER is a fast-growing area and is relatively unfamiliar to pharmaceutical statisticians, this book will be useful either as a general reference for those working in medical affairs or health technology assessment, or for those looking for a short introduction to a specific method (e.g., NMA)... In general, the book is quite readable without much prerequisite for statistical knowledge and will be useful to applied statisticians who are working in relevant areas or have an interest in CER."~Pharmaceutical Statistics
