This book employs a structured, question-based approach to evaluating clinical drug trials. The book includes eight sharply focused chapters, organized by the typical sections of a published article, and provides a basic overview of how to critique papers describing drug studies. Three chapters cover special topics in scientific literature evaluation. The book's well-established and effective instructional method refines and expands upon the scientific literature evaluation section of Ascione, Manifold and Parenti's textbook, Principles of Drug Information and Scientific Literature Evaluation (1994).
