High-Yield™ Biostatistics, Third Edition provides a concise review of the biostatistics concepts that are tested in the USMLE Step 1. Information is presented in an easy-to-follow format, with High-Yield Points that help students focus on the most important USMLE Step 1 facts. Each chapter includes review questions, and an appendix provides answers with explanations.This updated edition includes additional information on epidemiology/public health. The improved, more readable format features briefer, bulleted paragraphs, more High-Yield Points, and boldfaced terms. With CDROM.A Doody\'s Core Title for 2011 A comprehensive user-friendly introduction to biostatistics and epidemiology applied to medicine, clinical practice, and research. Features Presenting Problems (case studies) drawn from studies published in the medical literature, end-of-chapter, and a CD-ROM with data sets and statistical software programs. Useful in many areas of medicine and biology, Bayesian methods are particularly attractive tools for the design of clinical trials and diagnostic tests, which are based on established information, usually from related previous studies. Advanced Bayesian Methods for Medical Test Accuracy begins with a review of the usual measures such as specificity, sensitivity, positive and negative predictive value, and the area under the ROC curve. Then the scope expands to cover the more advanced topics of verification bias, diagnostic tests with imperfect gold standards, and those for which no gold standard is available.Promoting accuracy and efficiency of clinical trials, tests, and the diagnostic process, this book:Enables the user to efficiently apply prior information via a WinBUGS package Presents many ideas for the first time and goes far beyond the two standard references Integrates reader agreement with different modalities--X-ray, CT Scanners, and more--to study their effect on medical test accuracy Provides practical chapter-end problemsUseful for graduate students and consulting statisticians working in the various areas of diagnostic medicine and study design, this practical resource introduces the fundamentals of programming and executing BUGS, giving readers the tools and experience to successfully analyze studies for medical test accuracy. Early detection, or screening, is a common strategy for controlling chronic disease, but little information has been available to help determine which screening procedures are worthwhile, and how often, or to whom, they should be applied. This book presents the epidemiological methods that can be used to answer such questions. The book focuses on the description and measurement of changes in the natural history of disease brought about by early detection and treatment. Valid methods for assessing the usefulness of screening in reducing morbidity and mortality are emphasized and both experimental and nonexperimental studies are fully described. In addition, this work discusses the use of mathematical models in setting screening policy ways to enhance the feasibility of screening programs and the clinical course of screen-detected disease, separating the effects of early treatment, lead time, and length bias on outcome. The second edition has been updated throughout and considerably expanded. There are three new chapters: Cancer of the Breast Arteriosclerotic Vascular Disease and Cancer of the Cervix. These give concrete demonstrations of the applications of screening methods to important diseases. The Benefits of Reading Books,Most people read to read and the benefits of reading are surplus.
