COMPREHENSIVE META ANALYSIS HOW TO
We recently published a book called Common Mistakes in Meta-Analysis and How to Avoid Them With one more click you can export this to Word or PowerPoint. The program in Comparative Effectiveness and Outcomes Research at Duke University conducts multiple systematic reviews and meta-analyses each year for. The program combines ease of use with a wide array of computational options and sophisticated graphics. Additionally, with one click you can create a plot that shows the entire distribution of true effects. Comprehensive Meta-Analysis is a powerful computer program for meta-analysis. In Version 4 the program offers the option to display the prediction interval as part of the forest plot. Many guidelines for reporting a meta-analysis now request the inclusion of prediction intervals. This allows us to report, for example, that the mean effect size is a standardized mean difference of 0.50 but that in any single population the true effect size could be as low as 0.05 or as high as 0.95. This dispersion is addressed by the prediction interval. In any meta-analysis it is important to report the mean effect size and also how widely the effect size varies across studies. Or, from any screen in the program you can jump to the part of the video that explains all functions on that screen. You can watch one from start to finish to learn how to perform a meta-analysis and report it properly. This includes how to enter data, how to run the analysis, how to create plots, how to compare the effect size in different subgroups, and so on.Ĭritically, each section of the video explains now only how to perform specific functions, but what purpose these functions serve in the context of the analysis, and how to understand the meaning of the statistics.Įach case study runs about ninety minutes. We have developed videos of case studies that show how to run an analysis from start to finish. 1099), metaanalysis is a research method for systematically combining and synthesizing findings from multiple quantitative studies in a research domain. With a third click the program will export this document to Word Meta-analysis is used to aggregate effect relationships from multiple studies. With a second click the program will annotate this document and explain the meaning of all statistics as well as assumptions and limitations With one click the program will create a document that reports all statistics in a format that is suitable for publication.
