It includes chapters on methods typically used in medicine such as cumulative meta-analysis, and direct methods for combining odds ratios. Systematic reviews and meta-analysis are considered to be the highest quality evidence on a research topic because their study design reduces bias and produces more reliable findings. Decisions about the utility of an intervention or the validity of a hypothesis cannot be based on the results of a single study, because results typically vary from one study to the next. This book provides a clear and thorough introduction to meta-analysis, the process of synthesizing data from a series of separate studies. My students, who used pre-publication versions of some of the chapters, raved about the clarity of the explanations and examples. Larry Hedges, University of Chicago A pioneer in meta-analysis, Professor Hedges has published over 80 papers in the area many describing techniques he himself developed, that are now used as standard , co-edited the Handbook for Synthesis Research, and co-authored three books on the topic including the seminal Statistical Methods for Meta-Analysis. The meta-analysis serves to put the available data in context and to show the potential utility of the planned study.

Key ideas are introduced using text and figures, followed by the relevant formulas and worked examples. Having contributed chapters to two books on meta-analysis, she co-edited Publication Bias in Meta-Analysis. During each course week, you participate at times of your own choosing - there are no set times when you must be online. Produced by Jan Glover, David Izzo, Karen Odato and Lei Wang. The course assumes introductory knowledge of R.

Can I combine studies with different designs? Cochrane Library is a collection of six databases that contain different types of high-quality, independent evidence to inform healthcare decision-making, and a seventh database that provides information about Cochrane groups. These examples, as well as additional exercises and materials, may be downloaded from the book's web site www. She has authored several meta-analyses as well as articles on methodological issues in the area, and made numerous presentations on the topic. Borenstein, Hedges, Higgins, and Rothstein provide a refreshing departure from cookbook approaches with their clear explanations of the what and why of meta-analysis. Meta analysis is also widely used in basic research to evaluate the evidence in areas as diverse as sociology, social psychology, sex differences, finance and economics, political science, marketing, ecology and genetics, among others. As you move up the pyramid the amount of available literature on a given topic decreases, but the relevancy and quality of that literature increases.

At the beginning of each week, you receive the relevant material, in addition to answers to exercises from the previous session. Meta-analysis is the statistical procedure for combining data from multiple studies. He also helped to develop the best-selling software programs for statistical power analysis. For the more statistically sophisticated reader, the relevant formulas and worked examples provide a superb practical guide to performing a meta-analysis. He has much experience of teaching meta-analysis, both at Cambridge University and, by invitation, around the world.

The book provides an eclectic mix of examples from education, social science, biomedical studies, and even ecology. You have well-thought out curriculum that shows a respect for good pedagogy. Meta-analysis, by contrast, applies objective formulas much as one would apply statistics to data within a single study , and can be used with any number of studies. For anyone considering leading a course in meta-analysis, or pursuing self-directed study, Introduction to Meta-analysis would be a clear first choice. The book is ideal as a course textbook or for self-study.

It makes the discussion much more organic, relevant, useful, and enjoyable. Michael Borenstein, Director of Biostatistical Programming Associates Professor Borenstein is the co-editor of the recently published Wiley book Publication Bias in Meta-Analysis, and has taught dozens of workshops on meta-analysis. Berlin, ScD Introduction to Meta-Analysis is an excellent resource for novices and experts alike. The support staff are always helpful and respond quickly when questions arise. Note there is no full-text within this database.

Hannah Rothstein, Zicklin School of Business, Baruch College Professor Rothstein teaches regular seminars on meta-analysis and systematic reviews, and has 20 years of active research in the area of meta-analysis. See the Resources box below for instructions on locating systematic reviews and meta-analysis in the Library databases. During the week, you are expected to go over the course materials, work through exercises, and submit answers. Meta-analyses also play supporting roles in other papers. The book provides an eclectic mix of examples from education, social science, biomedical studies, and even ecology. Some funding agencies now require a meta-analysis of existing research as part of the grant application to fund new research. For the more statistically sophisticated reader, the relevant formulas, and worked examples provide a superb practical guide to performing a meta-analysis.

In other words, it provides an exhaustive summary of scholarly literature related to a particular research topic or question. Written by four of the leading names in meta analysis research, many points are explained visually by using screenshots from Excel spreadsheets and computer programs. The approach taken by Introduction to Meta-analysis is intended to be primarily conceptual, and it is amazingly successful at achieving that goal. PubMed systematic reviews cover a broad set of articles that build consensus on biomedical topics and medical genetics. The book takes a conceptual approach to meta-analysis, and for this reason has been widely embraced by the research community.

There will be a brief review of R programming in the first part of the course and links to other statistics. After completion of this course, students will know how to apply standard methods of meta-analysis in R and will also have gained more experience with advanced R programming topics, such as function writing and reproducible reporting. This book builds on this foundation and will serve equally well as the text for a course in meta-analysis, as a resource for self-study, or as a reference. Grant applications Meta-analyses are used in grant applications to justify the need for a new study. Rather, a mechanism is needed to synthesize data across studies. The graphical elements of the meta-analysis, such as the forest plot, provide a mechanism for presenting the data clearly, and for capturing the attention of the reviewers.

However, you may not always be able to find or need to find the highest level of evidence to answer your research question. That is, we make an intuitive argument that the meta-analysis should work in a particular way, and then show how the formula matches this goal. For the more statistically sophisticated reader, the relevant formulas and worked examples provide a superb practical guide to performing a meta-analysis. The reader can comfortably skip the formulas and still understand their application and underlying motivation. You apply real-world needs to the material being taught instead of having students memorize formulas or be confined within an academic-only practice of modeling. After installing R in your computer you may also install several R add-on packages. Options for Credit and Recognition: Students come to the Institute for a variety of reasons.
