Content

This elective course has a practical approach to the systematic review method and the meta-analysis tools. The systematic review method will include building a relevant search model, chosing the right databases for the topic, chosing in- and exclusion criterias, inclusion of studies, data extraction, and risk of bias assessment. The course will also have an analytic part where the students will learn to perform meta-analyses in STATA, including stratified analyses and eta-regressions. The goal for this study is to provide the students with enough experience to conduct a basic systematic review and meta-analysis, possibly as their master thesis.

Learning Outcome

After completed course, students are expected to be able to:

Knowledge

  • Explain how a literature search search can be made wider and how to make it more specific, by using search terms and Boolean operators.

  • Explain the differences between the biggest electronic databases and their content (Medline, Embase, Central and Clinicaltrials.gov).

  • Describe main characteristics for the most common quantitative study designs: case studies, case-control studies, cross sectional studies, cohort studies, randomized controlled trials, systematic reviews and meta-analyses.

  • Discuss the methodological quality of included studies, including risk of different types of bias.

  • Describe central epidemiological elements; odds ratios, relative risks, risk differences, means, medians, standard deviations, quantiles, and confidence intervals.

  • Describe the grounds for conducting different types of meta-analyses.

  • Describe relevant terms including heterogeneity, regression types and different types of meta-analyses.

Skills

  • Conduct a protocol for a systematic review and a meta-analysis that meets the requirements of PROSPERO.

  • Build a PICO model with relevant search terms.

  • Identify relevant studies in title/abstract and full text.

  • Use relevant methodological checklists on the included studies.

  • Identify and extract relevant information and results.

  • Choose a relevant statistical approach and the right types of analysis.

  • Illustrate results from risk of bias assessment and the analyses.

  • Discuss and use information on risk of bias, heterogeneity and precision.

  • Present the results and conclusion in a Summary of Findings (SoF) table by using the GRADE Approach.

Competences

  • Plan and perform a systematic literature search to identify most relevant literature according to the search question.

  • Evaluate methodological quality of the included studies, using relevant checklists.

  • Extract relevant results and information and use these in a meta-analysis.

  • Use stratified analyses and meta-regressions to explain heterogeneity in the results.

  • Make a statement on the estimate and the underlying evidence using a SoF table.

Literature will be uploaded to Absalon, along with relevant reading guides.

Software:

STATA Statistical Software will be used throughout the course. STATA software can be installed by SUND-IT on CSS room 2.01.02.

Epidemiology on a level that equals the course ’introduktion til epidemiologi’ and statistic knowledge on a level that equals the course ”introduktion til statistik”.
Lectures and group work including student presentation and plenum discussion of the assignments.
Continuous feedback during the course of the semester

Discussion and class activities will provide ongoing feedback about students understanding of the metods.
