The 2019 Methods Symposium was held virtually on Wednesday 5 February 2020 due to the cancelled 2019 Cochrane Colloquium. Full details and links to the recorded talks are available below.
Links to all of the recorded presentations and PDFs of the slides can be accessed via Cochrane Training.
Co-chairs: Professor Julian Higgins and Dr Joanne McKenzie
Cochrane Reviews are becoming increasingly complex as methods evolve, as data sources become more diverse, and as we increasingly recognize that health outcomes are the products of many interlinked elements. Cochrane pioneered the publication of protocols before undertaking systematic reviews, partly to help ensure that the many decisions we make along the way are objective and not based on the results of the identified studies.
The 2019 Methods Symposium examined whether our protocols continue to provide the road map we need to navigate a modern Cochrane Review. We explored how much can reasonably be anticipated about the decisions we need to make. Speakers addressed several aspects of pre-specification from diverse methodological perspectives, showcasing updated material in the new Cochrane Handbook for Systematic Reviews of Interventions (Version 6). Issues for discussion included what syntheses are to be performed, deciding which data to extract and analyse, and dealing with issues of complexity in interventions and study contexts. We discussed the extent to which issues can be overcome with careful review planning, and aimed to determine whether refinements are needed in our current guidance for writing protocols.
The Symposium was intended for the wider Cochrane community. The sessions were particularly useful for Cochrane Review Group editors, methodologists and others involved in review production, as well as those who are interested in understanding considerations for developing robust Cochrane Review protocols with increasingly diverse evidence.
Below is the programme with links to recordings of each of the talks (including PDFs of the slides) and to speaker biographies.
