RA3: Analysis Methods for Systematic Reviews

Introduction

RA3 is designed to target authors who have spent time working on their systematic review, are in the process of (or have just finished) study selection, and are now thinking about their analysis. This day enables authors to think through the appropriateness of their data collection form, and goes into further detail about analysis methods and models, and exploring heterogeneity.

Should I attend?

This workshop is suitable if you:

  • have attended workshops RA1 and RA2
  • have completed the protocol for your review
  • have developed and run your search for eligible papers
  • want to understand the meta-analysis methods for binary and continuous data types

What will be covered?

  • Meta-analysis methods for binary data (odds ratio, risk ratio, risk difference, NNTB/NNTH)
  • Meta-analysis methods for continuous data (mean difference, standardised mean difference)
  • Critical appraisal of your data collection form
  • Extracting data from research papers
  • Statistical methods for assessing heterogeneity
  • Subgroup and sensitivity analyses and when to use them
  • Fixed and random effects models
  • Assessing risk of bias with the Cochrane risk of bias tool

How is the workshop run?

This workshop comprises lectures and both individual and group practical exercises. Handouts of slides used in the lectures are provided.

What will I achieve?

By the end of the workshop, you should be able to:

  • understand and choose an appropriate method for summarising studies with binary and continuous outcome measures
  • refine your data collection form and commence the data extraction process
  • understand the methods for assessing and dealing with heterogeneity of study results
  • understand the use of the Cochrane risk of bias tool and modify it for your review
