A systematic review attempts to identify, appraise, and synthesize all the empirical evidence that meets pre-specified eligibility criteria to answer a specific research question. Meta-analysis is a quantitative, formal, epidemiological study design used to systematically assess the results of previous research to derive conclusions about that body of research. This course seeks to: Enhance students’ comprehension of key concepts and techniques related to systematic review and meta-analysis through focused lectures and assignments; and Equip students with practical skills necessary for conducting systematic reviews and meta-analyses through hands-on practices and programming exercises. Topics covered include: Fundamental concepts of systematic review and meta-analysis; Formulation of review topics; Development of review protocols; Determination of inclusion and exclusion criteria; Development of keyword search algorithms; Execution of forward and backward search methods; Management of references using Endnote; Utilization of data extraction tools; Assessment of study quality and bias; Determination and pooling of effect sizes across studies; Introduction to conducting meta-analyses using R, encompassing fixed-effect and random-effect meta-analysis; Exploration of meta-analysis with binary outcomes; Analysis of heterogeneity and meta-regression; Addressing small-study effects; Handling of missing data in meta-analysis; Implementation of multivariate meta-analysis; Meta-analysis of diagnostic test accuracy studies; and Execution of network meta-analysis. By the end of this course, students will possess an in-depth understanding of systematic review and meta-analysis concepts and techniques and will be adept at conducting such reviews and analyses using R.
