50 Studies Every Endocrinologist Should Know assembles landmark, evidence-based studies in classic endocrinology to guide readers towards solving thorny endocrine problems. Featuring a diverse range of study types--including RCTs, multicenter trials, observational studies, and meta-analyses--this volume addresses the core issues faced by endocrinologists in clinical practice. Each chapter provides a concise summary of key studies, highlighting results, limitations, and practical implications. The chapters conclude with a list of major take-home points, which collectively form a foundation of Endocrine Principles that can be applied to real-word patient problems. As with all books in the "50 Studies" series, each study was selected using an objective selection criterion that included citations per year, high levels of evidence, clinical studies and trials, and a 3-stage Delphi review by international experts in the field. It is an indispensable reference for fellows, physicians, nurse practitioners, and any primary providers with an interest in endocrinology, as well as those taking both the endocrinology board exam and the Endocrinology, Diabetes, & Metabolism certification exam.
