Preprints of the PRISMA 2020 papers are now available at @metaarxiv 🥳 The papers describe a major update of the main PRISMA reporting guideline for systematic reviews, reflecting advances in methods since the 2009 version. THREAD 👇
The PRISMA 2020 statement paper presents the revised checklists and flow diagram, outlining what we recommend authors report in systematic reviews (primarily those evaluating interventions) osf.io/preprints/meta…
The PRISMA 2020 explanation and elaboration paper explains why reporting of each item is recommended, presents bullet points that detail the reporting recommendations, and presents exemplars from published reviews osf.io/preprints/meta…
More exemplars for each item in PRISMA 2020 are available in this supplement osf.io/35gan/
We’ve also prepared a PRISMA 2020 development paper, which outlines the steps taken to update the PRISMA 2009 statement, and provides rationale for modifications to the original items osf.io/preprints/meta…
More details on the PRISMA 2020 development process are available in this supplement; mainly the results of our survey of methodologists and editors, and a summary of the meeting discussions and decisions osf.io/eqrhj/
Once the papers are published, we’ll update the PRISMA statement website with the latest checklists and templates, which will replace the current versions.
In future we’ll also release a web app for users to complete the PRISMA 2020 checklists online, currently being developed by the genius @mcguinlu
We’re really keen to hear your thoughts on PRISMA 2020 and the preprints we’ve shared, including any errors or aspects of the guideline that could be clearer. Other examples to add to our bank are welcome too!
Today marks two years since this dream team and I met to discuss updates to PRISMA. Working with them all (during a pandemic, no less) has been an utter joy, and I particularly want to thank my awesome co-leads @dmoher and @jomck15
