The Study Design and Statistics chapter of the 11th edition of the AMA Manual of Style begins with a description of the parts of a scientific manuscript and the role of each part: Abstract, Introduction, Methods, Results, and Discussion. The features unique to different study types are outlined: randomized clinical trials, parallel-design double-blind trials, crossover trials, equivalence and noninferiority trials, cluster trials, observational studies, cohort studies, case-control studies, case series, comparative effectiveness research, meta-analyses, cost-effectiveness/cost-benefit analyses, quality improvement studies, and survey studies. Because correct treatment depends on accurate diagnosis, attention is given to various types of diagnostic tests. A large glossary of statistical terms indicates the appropriate applications of commonly used statistical techniques, providing definitions, presentation, and tips and guidelines for correct usage. Many new terms have been added to this glossary since the previous edition.
