4 - 5 July 2018


Researchers trying to summarize the constantly growing body of published research are increasingly using meta-analysis. The focus of this 2-day course will be on concepts of linear models and mixed linear models in meta-analysis. The statistical software R will be used.


Day 1

  1. Introduction
    • Why perform a meta-analysis
    • Main steps of a meta-analysis
  2. Estimation of effect sizes of treatments
    • Effect sizes for continuous and categorical data (mean difference, odds ratio, etc.)
    • Estimation using linear and generalized linear fixed-effect models
    • Estimation using linear and generalized linear mixed-effect models
    • Sensitivity and uncertainty analysis of the estimated effect sizes
  3. Practical session 1
    • Analysis of a dataset by the participants using R
    • Discussion of the results

Day 2

  1. Regression methods for estimating relationships between variables
    • Definitions
    • Regression using linear, generalized linear, and nonlinear fixed-effect models
    • Regression using linear, generalized linear, and nonlinear mixed-effect models
    • Sensitivity and uncertainty analysis for regression models
  2. Practical session 2
    • Analysis of a dataset by the participants using R
    • Discussion of the results
  3. Quality criteria
    • Definitions of quality criteria
    • Assessment of a large number of meta-analyses
  4. Discussion and conclusion
