Clinical trials have become essential research tools for evaluating the benefits and risks of new interventions for the treatment and prevention of diseases, from cardiovascular disease to cancer to AIDS. Based on the authors’ collective experiences in this field, Introduction to Statistical Methods for Clinical Trials presents various statistical topics relevant to the design, monitoring, and analysis of a clinical trial. After reviewing the history, ethics, protocol, and regulatory issues of clinical trials, the book provides guidelines for formulating primary and secondary questions and translating clinical questions into statistical ones. It examines designs used in clinical trials, presents methods for determining sample size, and introduces constrained randomization procedures. The authors also discuss how various types of data must be collected to answer key questions in a trial. In addition, they explore common analysis methods, describe statistical methods that determine what an emerging trend represents, and present issues that arise in the analysis of data. The book concludes with suggestions for reporting trial results that are consistent with universal guidelines recommended by medical journals. Developed from a course taught at the University of Wisconsin for the past 25 years, this textbook provides a solid understanding of the statistical approaches used in the design, conduct, and analysis of clinical trials.

This volume presents a comprehensive and comprehensible set of guidelines for reporting the statistical analyses and research designs and activities commonly used in biomedical research.

From one of the world’s leading medical journals comes the definitive evidence-based, full-color guide to end-of-life and palliative care "...represents an important milestone in the evolution of care for people with advanced disease—-for which its editors and authors and JAMA should be rightly proud. It is wonderful that JAMA had the foresight to publish a series on this topic, which, as medicine has become more technologically advanced and subspecialized, is often overlooked and, sometimes worse, avoided....this book will be invaluable for front-line clinicians, and indeed all health care practitioners—as care at the close of life is a part of almost all of medicine’s specialties and settings."--Irene J. Higginson, BMBS, PhD, FPPHM, FRCP; Dept. of Palliative Care, Policy, & Rehabilitation; Cicely Saunders Institute; King's College London (from the foreword) A new addition to the JAMAevidence series, Care at the Close of Life: Evidence and Experience offers evidence-based and clinical expert guidance on caring for patients with life-limiting illness, incorporating the words and perspectives of affected patients, their families, and treating clinicians. Organized by these actual clinical cases, the book is based on the acclaimed 7-year series of 42 articles, originally published in JAMA as “Perspectives on Care at the Close of Life,” and now thoroughly updated as chapters and featuring extensive never-before-published material. Care at the Close of Life covers are a wide range of clinical syndromes, disease processes, communication challenges, health-care delivery settings, and issues faced by patients, including withdrawal of dialysis and other life-sustaining measures, cross-cultural approaches, and the role of chemotherapy. Throughout the book, emphasis is on the principles of palliative care, with the patient and family at the center of care, and with attention given to all problems—physical, psychological, social, and spiritual. Reflecting this focus, each chapter begins with a patient case study to introduce the clinical problem, followed by “perspectives” that draw on extensive, real-world dialogue between clinicians, patients, and families. Internationally renowned authors then review the typical challenges illustrated by the case, offering state-of-the-art, evidence-based assessment and treatment approaches. Features Fully revised and updated text with new evidence and references, including the search methodology for each chapter’s update Evidence-based orientation presents the current state of knowledge in the care of terminally ill patients and support for their families and caregivers Practical clinical guidance and approaches from international experts in palliative care Self-assessment Q&A, for reinforcing your knowledge of each chapter’s content and for preparing for exams A useful Glossary of acronyms, terms, and tests Updated Resources for each chapter offer current, authoritative sources of diagnostic and treatment information that can help you optimize palliative care Medline PubMed ID numbers facilitate quick, convenient access to references

The ultimate guide to the evidence-based clinical encounter "This book is an excellent source of supported evidence that provides useful and clinically relevant information for the busy practitioner, student, resident, or educator who wants to hone skills of physical diagnosis. It provides a tool to improve patient care by using the history and physical examination items that have the most reliability and efficiency."--Annals of Internal Medicine "The evidence-based examination techniques put forth by Rational Clinical Examination is the sort that can be brought to bear on a daily basis – to save time, increase confidence in medical decisions, and help decrease unnecessary testing for conditions that do not require absolute diagnostic certainty. In the end, the whole of this book is greater than its parts and can serve as a worthy companion to a traditional manual of physical examination."--Baylor University Medical Center (BUMC)Proceedings 5 STAR DOODY'S REVIEW! "Physical diagnosis has been taught to every medical student but this evidence-based approach now shows us why, presenting one of medicine's most basic tenets in a new and challenging light. The format is extraordinary, taking previously published material and updating the pertinent evidence since the initial publication, affirming or questioning or refining the conclusions drawn from the data. "This is a book for everyone who has studied medicine and found themselves doubting what they have been taught over the years, not that they have been deluded, but that medical traditions have been unquestionably believed because there was no evidence to believe otherwise. The authors have uncovered the truth. "This extraordinary, one-of-a-kind book is a valuable addition to every medical library."--Doody's Review Service Completely updated with new literature analyses, here is a uniquely practical, clinically relevant approach to the use of evidence in the content of physical examination. Going far beyond the scope of traditional physical examination texts, this invaluable resource compiles and presents the evidence-based meanings of signs, symptoms, and results from physical examination maneuvers and other diagnostic studies. Page after page, you'll find a focus on actual clinical questions and presentations, making it an incomparably practical resource that you'll turn to again and again. Importantly, the high-yield content of The Rational Clinical Examination is significantly expanded and updated from the original JAMA articles, much of it published here for the first time. It all adds up to a definitive, ready-to-use clinical exam sourcebook that no student or clinician should be without. FEATURES Packed with updated, new, and previously unpublished information from the original JAMA articles Standardized template for every issue covered, including: Case Presentation; Why the Issue Is Clinically Important; Research and Statistical Methods Used to Find the Evidence Presented; The Sensitivity and Specificity of Each Key Result; Resolution of the Case Presentation; and the Clinical Bottom Line Completely updated with all-new literature searches and appraisals supplementing each chapter Full-color format with dynamic clinical illustrations and images Real-world focus on a specific clinical question in each chapter, reflecting the way clinicians approach the practice of evidence-based medicine More than 50 complete chapters on common and challenging clinical questions and patient presentations Also available: JAMAevidence.com, a new interactive database for the best practice of evidence based medicine

Healthcare decision makers in search of reliable information that compares health interventions increasingly turn to systematic reviews for the best summary of the evidence. Systematic reviews identify, select, assess, and synthesize the findings of similar but separate studies, and can help clarify what is known and not known about the potential benefits and harms of drugs, devices, and other healthcare services. Systematic reviews can be helpful for clinicians who want to integrate research findings into their daily practices, for patients to make well-informed choices about their own care, for professional medical societies and other organizations that develop clinical practice guidelines. Too often systematic reviews are of uncertain or poor quality. There are no universally accepted standards for developing systematic reviews leading to variability in how conflicts of interest and biases are handled, how evidence is appraised, and the overall scientific rigor of the process. In Finding What Works in Health Care the Institute of Medicine (IOM) recommends 21 standards for developing high-quality systematic reviews of comparative effectiveness research. The standards address the entire systematic review process from the initial steps of formulating the topic and building the review team to producing a detailed final report that synthesizes what the evidence shows and where knowledge gaps remain. Finding What Works in Health Care also proposes a framework for improving the quality of the science underpinning systematic reviews. This book will serve as a vital resource for both sponsors and producers of systematic reviews of comparative effectiveness research.
