Meta-analysis denotes the quantitative aggregation (research synthesis) across multiple scientific studies. This course aims at understanding and applying the core concepts and the workflow to conduct a meta-analysis. It is structured along a working example to learn and perform the different steps of a standard meta-analysis: hypothesis formulation, literature search, data extraction, statistical analysis, presentation, assessment of potential bias. Each step will be introduced by a lecture, followed by the joint working example. At the end, the group of participants will have conducted their own meta-analysis.

Specific Topics:
➢ Understanding the aims and core concepts of meta-analysis
➢ Searching and compiling relevant published literature
➢ Extracting effect sizes from published studies
➢ Conducting statistical analyses across effect sizes
➢ Creating summary figures
➢ Conducting bias and sensitivity analyses

The workshop will prepare participants to compile their own datasets. They will become familiar with the basic workflow of meta-analyses and will become capable to conduct their own analyses.

Didactic Elements
The workshop will consist of lectures, practical exercises, and discussions together with a joint working example.

You will need
Basic knowledge of statistics in R
Own laptop with R and R studio installed

Expected performance
Active participation, independent analysis of the course data sets, writing of own R code, short presentation of own results.
