An Introduction to Multivariate Meta-analysis presented by Malcolm Price, Richard Riley, Jamie Kirkham on 8 June 2016 Venue: The Royal Statistical Society, 12 Errol Street, London, EC1Y 8LX Nearest Tube stations: Barbican, Liverpool Street, Moorgate, Old Street Course Summary: The use of meta-analysis to synthesise effect estimates from multiple studies is now well established in evidence based medicine. Many studies have more than one outcome of interest, such as diseasefree survival and overall survival, and researchers currently meta-analyse each outcome separately. However, such multiple outcomes are often related to each other, i.e. they are correlated. For example, a patient’s time to recurrence of disease is generally associated with their time of death. By meta-analysing each outcome independently, researchers ignore this correlation and thus lose potentially valuable information. However, a multivariate meta-analysis can analyse correlated outcomes together and utilise their correlated information to get the most out of the available data. The course provides a firm introduction to multivariate meta-analysis methods and gives a full demonstration of its implementation in STATA. Learning Outcome: To develop an understanding of the rational, methods, advantages and limitations of multivariate meta-analysis. Topics Covered: The course begins by revising the well-known methods for univariate meta-analysis. Next it introduces the multivariate meta-analysis model for both fixed and random effects. This includes the rational, mathematical form, and a description of its advantages and disadvantages as compared to the univariate approach. It explains how to calculate within-study and between-study correlations, and show why they lead to 'borrowing of strength' across outcomes. It details estimation methods to fit the multivariate model, and provide a detailed demonstration of the MVMETA package in STATA. Next the presenters discuss some of latest developments in the field, including a multivariate equivalent of the I-squared statistic, and outcome reporting bias. Finally, the course gives a more in-depth description of one particular application of multivariate meta-analysis – the synthesis of summary evidence from diagnostic test studies. Target Audience: Statisticians interested in learning about evidence synthesis, especially in a clinical/epidemiological setting. Knowledge Assumed: A reasonable grounding in statistics is required. Some knowledge of meta-analysis and randomised controlled trials would be of help, but is not essential. Delegate comments: “Excellent course - very interesting and very experienced and knowledgeable presenters.” “Well organised and well-structured course” “Very well prepared course at about the right level. Will allow me to access the literature now!” Course Format: Registration begins at 09.30 and the course runs from 10.00 until 17.00. The course consists of lectures including a class demonstration of the MVMETA package in STATA.
