This series features some of the best and most popular texts in epidemiology and biostatistics under the editorship of the major authorities in the field. The books cover subjects of interest primarily to epidemiologists, although many of the subjects covered will interest physicians in other areas of medicine as well as medical statisticians, public health physicians, and researchers. Most volumes are concerned with the methodology of epidemiological research, but several cover the epidemiology of specific medical disorders and specific exposures.
